Top 100 Secondary 4 Academic Verbs | Grade 10 Command Words for Essays, Analysis and Evaluation

This Secondary 4 academic verbs guide teaches the Grade 10 command words and directive verbs students meet in essays, reading comprehension, source work, Science, Mathematics, Humanities and other academic tasks. It is built for students searching for 10th grade command words, academic verbs for essays, and the meaning of instructions such as analyse, evaluate, justify, compare, contrast, explain, discuss, interpret and synthesize.

Knowing the topic is not enough if the student answers the wrong operation. A Grade 10 question that says describe does not ask for the same response as one that says explain; compare is not identical to contrast; evaluate needs judgement against criteria; justify needs reasons that defend a choice or conclusion. These Secondary 4 command words with meanings and examples therefore connect each verb to the kind of thinking, evidence and answer structure it normally requires.

This longform Grade 10 academic verbs article combines command-word definitions, answer architecture, academic vocabulary, worked examples, wrong-mode answers, cross-subject transfer, worksheets, retrieval practice and quizzes. Exact command-word expectations can vary by subject, syllabus, examination board and mark scheme, so students should always check the instructions used in their own course. The purpose here is broader: build a transferable map from verb → thinking operation → evidence requirement → answer form.

This page extends the Secondary 4 / Grade 10 academic-vocabulary flagship, the vocabulary practice system, the academic collocations guide, the synonyms and antonyms precision guide, and the morphology guide. Those pages own their existing jobs. This page owns academic verbs as instructions for thinking and answering.

The command word is not decoration. It tells you what kind of answer the question is built to receive.

The 60-second answer

• Define → state the meaning or boundary of a concept.
• Describe → state relevant features, characteristics or what happens.
• Explain → show why or how something happens using a mechanism, reason or relationship.
• Compare → examine similarities and differences on shared dimensions.
• Contrast → foreground meaningful differences.
• Analyse → break something into parts or relationships and explain how they work together.
• Interpret → explain meaning or significance from evidence, text or data.
• Evaluate → judge quality, effectiveness, importance or validity against relevant criteria.
• Justify → defend a choice or conclusion with reasons and evidence.
• Discuss → examine an issue from relevant angles, often including competing considerations.
• Synthesize → combine multiple ideas or sources into a new coherent understanding.
• Command words vary by assessment system. Use this guide as a transferable thinking map, then confirm the exact local mark-scheme expectation.

Why students lose marks even when they know the content

A student can know the facts and still answer the wrong question. If the instruction says evaluate and the student only describes, the response may be accurate yet incomplete. If the instruction says compare and the student writes two separate summaries with no relational language, the content may be correct but the comparison operation is missing. If the instruction says justify and the student merely states a preference, the answer lacks the reasons that make the choice defensible.

Academic verbs therefore behave like routing instructions. They tell the student what to do with knowledge. Some ask for retrieval. Some ask for representation. Some require causal explanation. Some require classification or relationship. Some require evidence-based judgement. Some require integration across sources. Secondary 4 becomes difficult partly because questions increasingly move from “What do you know?” to “What can you do with what you know?”

A strong student learns to convert the verb into an answer procedure before writing. That procedure should remain flexible because subjects differ. “Evaluate” in Mathematics may involve checking a result against conditions; “evaluate” in History may require source judgement; “evaluate” in an essay may require criteria, evidence, counterconsiderations and a reasoned overall conclusion. The core operation—judgement against relevant grounds—remains, while disciplinary evidence changes.

The command-word equation

command verb → thinking operation → evidence/knowledge needed → answer structure → check against question

Example:

Evaluate the effectiveness of the intervention. → define the intended outcome → examine evidence of results → consider limitations and relevant criteria → judge how effectively the intervention achieved the intended outcome → qualify the conclusion where evidence is incomplete.

Another:

Compare the two explanations. → choose shared dimensions → examine both explanations on each dimension → state similarities and differences relationally → identify the most important relationship if the task requires it.

Part I — Recall and representation verbs

1. Define

Core operation: state the meaning, scope or essential boundary of a concept. Typical answer shape: “X is…” followed by defining features that distinguish it from nearby concepts. Do not: replace the definition with an example only. Wrong-mode answer: “Equity is when one school receives extra support.” That illustrates but does not fully define. Stronger answer: “Equity is a principle of fairness that may allocate different support according to relevant differences in need or barriers.” Cross-subject transfer: define a mathematical term, scientific process, literary device or social concept. Check: could the reader tell what is included and excluded?

2. Describe

Core operation: state relevant features, characteristics, sequence or what is observed. Typical answer shape: organised account of what is present or what happens. Do not: automatically add causes unless the question also asks why. Wrong-mode answer: explaining the mechanism when only a concise description is required can waste time. Example: “The graph rises gradually from January to April, remains stable in May, and then declines sharply in June.” Boundary: description answers “what”; explanation usually answers “how/why”. Cross-subject transfer: describe a trend, setting, experiment result, procedure or historical condition.

3. Identify

Core operation: recognise and name the relevant item, feature, cause, pattern or example. Typical answer shape: direct naming, sometimes with brief evidence if required. Do not: write a full essay when the task only asks identification. Example: “The main limitation is the small, self-selected sample.” Boundary: identification is often the first step before explanation or evaluation. Cross-subject transfer: identify a variable, quotation technique, source limitation, algebraic form, geographical feature or causal factor. Check: have you selected the item the question asks for, rather than a nearby but irrelevant fact?

4. Label

Core operation: attach the correct term, symbol or name to a feature. Typical answer shape: concise word, phrase or notation placed accurately. Do not: substitute a general description when a precise label is expected. Example: label the independent variable, axis, cell component, rhetorical feature or part of a diagram. Boundary: labelling tests recognition and terminology more than extended reasoning. Cross-subject transfer: common in diagrams, graphs, grammar, Science and Mathematics. Check: is the label exact enough for the assessed convention?

5. List

Core operation: provide several relevant items, usually briefly and without extended explanation unless requested. Typical answer shape: ordered or unordered set of correct points. Do not: spend excessive time elaborating one item if marks depend on multiple distinct items. Example: “List three factors affecting demand: price, income and consumer preferences.” Boundary: list is usually breadth-oriented. Cross-subject transfer: list causes, properties, stages, examples, variables or features. Check: are the items distinct, relevant and sufficient in number?

6. Name

Core operation: supply the correct term or entity. Typical answer shape: very concise response. Do not: confuse “name” with “explain”. Example: “Name the process by which water vapour becomes liquid: condensation.” Boundary: a naming item often tests whether the concept is retrievable from a description. Cross-subject transfer: name a theorem, process, person, structure, technique or category. Check: spelling and terminology may matter more because the answer is short.

7. Outline

Core operation: give the main features, stages or structure without full detail. Typical answer shape: concise skeleton of the process or argument. Do not: provide either a one-word answer or a fully developed essay unless the context demands it. Example: “Outline the stages of the investigation: formulate a hypothesis, collect data, analyse results, evaluate limitations and conclude.” Boundary: outline is broader than list because relationships or sequence may matter, but it is less developed than explain. Cross-subject transfer: outline procedures, arguments, events or plans.

8. Recall

Core operation: retrieve learned information from memory. Typical answer shape: fact, formula, term, definition or previously learned relationship. Do not: overcomplicate straightforward retrieval. Example: recall a formula, date, vocabulary meaning or law. Boundary: recall is a cognitive operation more than a common explicit exam command in some subjects, but it is foundational because higher-order verbs depend on accessible knowledge. Cross-subject transfer: every discipline. Check: can the fact be retrieved without cues, and is it the exact fact the question needs?

9. State

Core operation: express a fact, rule, conclusion or position clearly and directly. Typical answer shape: concise declarative sentence. Do not: add unsupported explanation when only the statement is required, though some mark schemes may reward necessary qualification. Example: “State the relationship: as temperature increases, resistance increases under the conditions shown.” Boundary: state is often shorter than explain or justify. Cross-subject transfer: state a law, result, thesis, condition or relationship. Check: is the statement complete enough to stand on its own?

10. Summarise

Core operation: compress the essential content while preserving the main meaning and relationships. Typical answer shape: shorter restatement centred on main claim, evidence or sequence. Do not: copy large sections, include minor detail, or change claim strength. Example: summarise a passage by stating the writer’s central position, key reason and important qualification. Boundary: summary reduces length; synthesis combines sources into a new structure. Cross-subject transfer: texts, findings, historical developments and project outcomes. Check: if the original disappeared, would the summary preserve what matters most?

Part II — Explanation and clarification verbs

11. Account

Core operation: explain or give reasons for a result, pattern or event; in some contexts, “account for” means explain why something occurred. Typical answer shape: relevant mechanism or reasons linked to the observed outcome. Do not: treat account as a universal synonym for describe. Example: “Account for the decline in participation” requires reasons that explain the decline. Boundary: exact use varies by discipline and examination board. Cross-subject transfer: Geography, History, Economics, Science and data interpretation. Check: have you explained the observed pattern rather than merely repeated it?

12. Clarify

Core operation: make an idea, distinction or statement clearer and less ambiguous. Typical answer shape: precise re-expression, definition, distinction or added explanatory detail. Do not: merely add words. Example: clarify “access” by explaining that it means practical ability to use a service, not mere availability. Boundary: clarification can preserve complexity while removing confusion. Cross-subject transfer: essays, definitions, methods and oral discussion. Check: what exact ambiguity or uncertainty has been removed?

13. Demonstrate

Core operation: show clearly through reasoning, evidence, calculation or performance. Typical answer shape: evidence or steps that make the proposition visible. Do not: use one weak anecdote to claim a general proposition has been demonstrated. Example: in Mathematics, demonstrate a result through valid working; in English, demonstrate understanding through well-selected evidence. Boundary: the evidential strength of demonstrate depends on discipline. Cross-subject transfer: Mathematics, Science, practical tasks and essays. Check: is the showing strong enough for the claim?

14. Elaborate

Core operation: develop an idea with more detail, explanation, examples or implications. Typical answer shape: initial point followed by expansion that adds meaning rather than repetition. Do not: restate the same sentence in longer wording. Example: “Public transport improves access.” Elaborate by explaining which barriers are reduced, which groups benefit and under what conditions. Boundary: elaboration deepens a point; evidence may be one way to elaborate. Cross-subject transfer: essays, presentations and explanations. Check: has the reader learned something new after the elaboration?

15. Exemplify

Core operation: provide an example that represents or illustrates a concept. Typical answer shape: concept + relevant example + brief explanation of fit if needed. Do not: assume one example proves frequency or causation. Example: exemplify a trade-off by showing a policy that improves access but increases cost. Boundary: exemplification clarifies membership or operation; demonstration may require stronger evidence. Cross-subject transfer: vocabulary, theory, literature, Science and social subjects. Check: does the example clearly instantiate the idea?

16. Explain

Core operation: show how or why something happens, works or follows. Typical answer shape: claim or observation → mechanism/reason → link back to outcome. Do not: substitute description for explanation. Example: “Explain why attendance fell” requires a causal or reasoning link, not merely “attendance fell after Week 4.” Boundary: explanation may be causal, functional, logical or interpretive depending subject. Cross-subject transfer: universal. Check: does the answer contain the “because/how this leads to that” relationship the question requires?

17. Illustrate

Core operation: make an idea clearer using an example, case, diagram or representation. Typical answer shape: idea + illustrative case. Do not: treat the illustration as proof of a general claim. Example: illustrate opportunity cost with a student choosing between two mutually exclusive uses of time. Boundary: illustration aids understanding; evidence establishes or supports claims. Cross-subject transfer: Economics, English, Science, Mathematics and Humanities. Check: does the case reveal the concept more clearly?

18. Paraphrase

Core operation: restate meaning in different wording while preserving scope, certainty and logical relationship. Typical answer shape: new syntax and vocabulary with the same essential proposition. Do not: perform synonym substitution word by word or strengthen “may” into “will”. Example: “may contribute to” can be paraphrased as “could play a part in”, not “causes”. Boundary: paraphrase preserves one source’s meaning; synthesis integrates multiple sources. Cross-subject transfer: comprehension, research and note-making. Check: has any claim strength or condition changed?

19. Restate

Core operation: express the same proposition again, usually more clearly or in a different form. Typical answer shape: concise reformulation. Do not: add a new claim when only restatement is needed. Example: restate a thesis in the conclusion without copying it verbatim. Boundary: restate is often closer to the original structure than paraphrase, though usage overlaps. Cross-subject transfer: writing, oral explanation and problem solving. Check: is the core meaning unchanged but clearer or better fitted to context?

20. Translate

Core operation: convert information from one representational system, language or form into another while preserving relevant meaning. Typical answer shape: language-to-language, words-to-equation, graph-to-prose, prose-to-diagram or technical-to-plain-language transformation. Do not: assume translation is mechanical; meaning must be preserved. Example: translate “twice a number plus five” into an algebraic expression, or translate a graph trend into a verbal statement. Boundary: exact expectations differ strongly by discipline. Cross-subject transfer: language, Mathematics, Science and data literacy. Check: has the information survived the change of form?

Part III — Comparison, classification and relationship verbs

21. Categorise

Core operation: place items into groups according to defined characteristics. Typical answer shape: categories + membership rule + assigned items. Do not: group randomly or after seeing the desired conclusion. Example: categorise vocabulary by function: evidence verbs, evaluation verbs and synthesis verbs. Boundary: categorisation creates or uses grouping principles; classification often uses an established system. Cross-subject transfer: Biology, vocabulary, data analysis, Humanities and research. Check: is the rule for membership clear and consistently applied?

22. Classify

Core operation: assign items to recognised classes using relevant criteria. Typical answer shape: item → class → reason/evidence if required. Do not: confuse naming a class with explaining why the item belongs there. Example: classify a variable as independent, dependent or controlled. Boundary: classification is often more formal or system-based than casual grouping. Cross-subject transfer: Science, Mathematics, language and social research. Check: have you used the classification system the subject expects?

23. Compare

Core operation: examine two or more items on shared dimensions, identifying similarities and differences where relevant. Typical answer shape: dimension 1: A versus B; dimension 2: A versus B; relational conclusion if needed. Do not: write two separate mini-essays with no linking comparison. Example: compare two sources by purpose, evidence and reliability. Boundary: some boards use compare to include both similarities and differences; others specify their conventions more narrowly. Cross-subject transfer: universal. Check: can the reader see the relationship directly?

24. Connect

Core operation: show how ideas, events, variables, texts or systems relate. Typical answer shape: A relates to B because… or A influences B through… Do not: assert a link without explaining its basis. Example: connect source reliability to the confidence of a historical conclusion. Boundary: connection can be causal, thematic, structural, temporal or conceptual. Cross-subject transfer: interdisciplinary tasks, essays and systems thinking. Check: have you named the type of relationship, not merely said “they are connected”?

25. Contrast

Core operation: foreground meaningful differences between items on shared dimensions. Typical answer shape: explicit A-versus-B statements. Do not: include irrelevant differences that do not matter to the question. Example: contrast efficiency with effectiveness: one concerns resource use, the other goal achievement. Boundary: contrast differs from compare because difference is central, although assessment conventions vary. Cross-subject transfer: texts, methods, systems, sources and theories. Check: is each difference stated relationally and tied to the task?

26. Differentiate

Core operation: show how related items differ, often by identifying the feature that separates them. Typical answer shape: concept A → defining feature; concept B → contrasting feature; explicit separation. Do not: give two definitions without making the difference visible. Example: differentiate correlation from causation by explaining that correlation is association while causation requires evidence that one factor produces change in another. Boundary: differentiate often asks for the basis of separation; distinguish can be used similarly. Cross-subject transfer: Science variables, literary techniques, mathematical forms and social concepts. Check: could the reader tell exactly where one concept stops and the other begins?

27. Distinguish

Core operation: recognise and state a meaningful difference between closely related ideas, cases or categories. Typical answer shape: “A differs from B because…” or a contrast table. Do not: list unrelated properties. Example: distinguish reliability from validity: reliability concerns consistency, whereas validity concerns whether the method or measure is appropriate for the intended construct. Boundary: in many contexts distinguish and differentiate overlap, but distinguish often emphasises conceptual recognition and boundary control. Cross-subject transfer: vocabulary, Science methods, source evaluation and Mathematics. Check: is the difference relevant to the problem?

28. Group

Core operation: place items together because they share a relevant property. Typical answer shape: set of groups + stated basis. Do not: create groups whose membership rule changes from item to item. Example: group academic verbs into recall, analysis, evaluation and synthesis operations. Boundary: group is often less formal than classify; the assessed task may care more about the chosen organizing principle than a predefined taxonomy. Cross-subject transfer: data, vocabulary, organisms, geometric objects and historical causes. Check: can every item’s membership be justified using the same rule?

29. Relate

Core operation: show how one idea, event, variable or text connects to another. Typical answer shape: relationship statement + explanation of the link. Do not: merely mention both items. Example: relate increased transport frequency to improved access by explaining how shorter waiting times reduce a practical barrier. Boundary: the relationship might be causal, comparative, thematic, proportional or structural; name which. Cross-subject transfer: graph interpretation, literature, Science and Humanities. Check: have you explained the nature of the relationship rather than saying only that a relationship exists?

30. Sequence

Core operation: arrange stages, events or steps in the correct order. Typical answer shape: first → next → then → final, with causal or procedural links if required. Do not: confuse chronology with causation. Example: sequence the stages of an investigation from question to hypothesis, data collection, analysis, evaluation and conclusion. Boundary: sequence tells order; explain tells why the stages or events follow. Cross-subject transfer: History chronology, Science procedures, writing plans, algorithms and processes. Check: is the order correct, and are any essential stages missing?

Part IV — Analysis and interpretation verbs

31. Analyse

Core operation: break material into meaningful parts or relationships and explain how those parts contribute to the whole. Typical answer shape: identify feature → examine relationship/function → explain significance. Do not: treat analysis as quotation spotting or description. Example: analyse a paragraph by identifying the claim, the evidence, the assumption and the way they interact. Boundary: analysis does not always require judgement; evaluation adds criteria and judgement. Cross-subject transfer: texts, data, systems, sources and mathematical reasoning. Check: have you explained how the parts work, not merely named them?

32. Annotate

Core operation: add concise explanatory notes to a text, diagram, graph, source or working. Typical answer shape: selected feature + short note naming function, meaning or significance. Do not: highlight everything or copy the text into the margin. Example: annotate a source by marking the writer’s claim, evidence, tone shift and limitation. Boundary: annotation supports later analysis; it is not itself a complete analytical answer. Cross-subject transfer: English, History, Science diagrams and Mathematics worked solutions. Check: does each note add useful interpretation rather than visual clutter?

33. Deconstruct

Core operation: take apart a complex structure, argument or representation to expose how it is built. Typical answer shape: component map + relationships + assumptions or design choices. Do not: use the term merely as a more impressive synonym for analyse. Example: deconstruct a persuasive advertisement into audience, claim, emotional appeal, evidence and omitted information. Boundary: in literary theory, deconstruct can have a specific theoretical meaning; in general educational use it often means systematic unpacking. Cross-subject transfer: arguments, systems and media. Check: has the original whole become easier to understand because its construction is visible?

34. Detect

Core operation: discover or notice the presence of a feature, signal, error, pattern or condition. Typical answer shape: identify the feature + evidence of its presence. Do not: claim detection when the evidence is ambiguous without qualification. Example: detect bias in a survey design by noticing that the sampling method systematically excludes one group. Boundary: detection locates a feature; diagnosis explains the underlying problem or mechanism. Cross-subject transfer: error analysis, experiments, sources, reading and data. Check: what observable clue makes the feature detectable?

35. Diagnose

Core operation: identify the underlying cause or weak link responsible for a problem or pattern. Typical answer shape: symptom → evidence → likely cause → distinction from alternatives. Do not: label the symptom as the diagnosis. Example: a student repeatedly misses inference questions; diagnosis may show the weak link is not vocabulary meaning but failure to connect textual clues. Boundary: diagnosis is causal and discriminative; detection merely notices that something is wrong. Cross-subject transfer: learning errors, system faults, scientific reasoning and case studies. Check: does the proposed cause explain the observed pattern better than competing explanations?

36. Examine

Core operation: inspect a topic, source, assumption, process or piece of evidence closely and systematically. Typical answer shape: relevant aspects → close scrutiny → explanation of what they reveal. Do not: treat examine as “mention”. Example: examine the assumption that every household can use an online-only service by considering device access, connectivity, digital skill and language. Boundary: examine is broad; a particular subject may expect analysis, explanation or evaluation within it. Cross-subject transfer: almost universal. Check: have the important aspects been inspected rather than skimmed?

37. Infer

Core operation: reach a reasonable conclusion from clues that do not state the answer directly. Typical answer shape: inference + specific evidence + explanation of the link. Do not: invent information unsupported by the source. Example: infer that a character is hesitant from pauses, incomplete sentences and repeated qualification. Boundary: writers imply; readers infer. Cross-subject transfer: comprehension, source-based history, graph interpretation, Science and case studies. Check: could another reader trace the inference back to the evidence?

38. Interpret

Core operation: explain the meaning, significance or implication of information, language, behaviour or data. Typical answer shape: evidence → plausible meaning → contextual justification. Do not: confuse interpretation with free opinion. Example: interpret a small increase cautiously as possible improvement rather than proof of success. Boundary: interpretation assigns meaning; description reports what is present. Cross-subject transfer: literature, graphs, sources, experiments and statistics. Check: is the interpretation constrained by evidence and context?

39. Investigate

Core operation: examine a question systematically by gathering and analysing relevant information. Typical answer shape: question → method → evidence/data → analysis → conclusion. Do not: treat casual searching as investigation. Example: investigate whether longer opening hours increase library use by defining a measure, collecting comparable data and considering alternative explanations. Boundary: investigate is often a whole-task verb that contains several smaller operations. Cross-subject transfer: Science, Geography, projects and case studies. Check: is the method capable of answering the question?

40. Trace

Core operation: follow the development, origin, sequence or pathway of something across time, stages or sources. Typical answer shape: starting point → significant stages → present outcome. Do not: list events without showing continuity or change. Example: trace the development of a policy from public concern to proposal, pilot, implementation and revision. Boundary: trace emphasises pathway; explain asks why the changes happened. Cross-subject transfer: History, literature, Science processes, argument development and data lineage. Check: is the route from origin to outcome visible?

Part V — Application and construction verbs

41. Adapt

Core operation: modify a method, idea, text or solution to fit new conditions while preserving relevant function. Typical answer shape: original approach → new constraint → justified modification. Do not: copy the original unchanged. Example: adapt a revision plan for a student who has only thirty minutes per day by preserving retrieval and spacing while reducing volume. Boundary: adaptation changes fit; transformation may involve deeper structural change. Cross-subject transfer: design, writing, problem solving and learning strategies. Check: does the adapted version still accomplish the intended job?

42. Apply

Core operation: use a rule, concept, method or framework in a particular case. Typical answer shape: relevant principle → case details → correct use → result. Do not: repeat the theory without using it. Example: apply the criterion of reliability to a measuring instrument by examining consistency across repeated measurements. Boundary: application requires transfer; recall alone is insufficient. Cross-subject transfer: formulas, theories, grammar rules, evaluation frameworks and case studies. Check: has the abstract knowledge changed how the specific case is handled?

43. Calculate

Core operation: obtain a numerical result through appropriate mathematical operations. Typical answer shape: formula or relationship → substitution → working → result with units/precision where needed. Do not: give an unexplained number if method marks or units matter. Example: calculate percentage change from initial and final values. Boundary: calculate produces a value; interpret explains what that value means. Cross-subject transfer: Mathematics, Science, Economics and data tasks. Check: is the method valid, arithmetic correct, and answer expressed at the expected precision?

44. Construct

Core operation: build a representation, argument, diagram, proof, model or response from specified components or constraints. Typical answer shape: planned structure with all required elements. Do not: merely describe what could be built. Example: construct an argument using a claim, reason, evidence, counterargument and qualified conclusion; or construct a geometric figure under defined conditions. Boundary: construct is productive: something must be made. Cross-subject transfer: Mathematics, writing, design and Science. Check: does the constructed object satisfy every stated constraint?

45. Derive

Core operation: obtain a result, formula, conclusion or relationship from known principles or preceding information. Typical answer shape: starting assumptions → valid steps → resulting expression or conclusion. Do not: jump directly to a remembered formula when derivation is requested. Example: derive an expression from a general relationship or derive a conclusion from stated premises. Boundary: derive emphasises the route from source to result. Cross-subject transfer: Mathematics, Physics, logic and language analysis. Check: can every step be justified from what came before?

46. Estimate

Core operation: produce a reasonable approximate value or judgement using available information. Typical answer shape: assumptions → approximation method → approximate result. Do not: present an estimate with false precision. Example: estimate the number of daily users from a sample period and stated operating hours. Boundary: estimate is deliberately approximate; calculate may seek a more exact result. Cross-subject transfer: Mathematics, Science, planning and data interpretation. Check: are the assumptions reasonable, and is the degree of precision honest?

47. Formulate

Core operation: create a clear, structured statement such as a hypothesis, argument, question, rule or plan. Typical answer shape: precise wording that can guide later reasoning or testing. Do not: confuse formulation with proof or evaluation. Example: formulate a hypothesis linking sleep duration and concentration in a testable way. Boundary: formulate creates the proposition; test examines it. Cross-subject transfer: Science, essays, research and Mathematics. Check: is the formulated statement specific enough to use?

48. Model

Core operation: represent a system, relationship or process in a simplified form that preserves relevant features. Typical answer shape: assumptions + representation + variables/relationships + limits. Do not: confuse a model with the real system. Example: model population growth using a mathematical relationship, then state the conditions under which the model is useful. Boundary: models simplify; evaluation asks where the simplification breaks. Cross-subject transfer: Mathematics, Science, Economics and systems thinking. Check: what does the model preserve, and what does it omit?

49. Solve

Core operation: find a correct resolution to a defined problem under the relevant conditions. Typical answer shape: problem representation → method → working/reasoning → answer → verification where useful. Do not: treat a partial reduction of the problem as a full solution. Example: solve an equation, solve an optimisation problem, or propose a solution to a case-study problem while meeting constraints. Boundary: in open problems, “solve” may require judgement about whether all important requirements are satisfied. Cross-subject transfer: Mathematics, Science and applied tasks. Check: does the answer actually resolve the stated problem?

50. Use

Core operation: employ given information, a source, formula, method or representation to complete a task. Typical answer shape: select the relevant material → apply it correctly → produce the requested result. Do not: reproduce the material without doing anything with it. Example: use Source A to explain why the policy faced opposition; use the graph to estimate a value; use a formula to calculate energy. Boundary: “use” is deliberately broad and the object tells you the actual operation. Cross-subject transfer: universal. Check: is the supplied material visibly doing work in the answer?

Part VI — Evaluation and judgement verbs

51. Appraise

Core operation: judge value, quality or performance using relevant standards. Typical answer shape: criteria → evidence → strengths/weaknesses → reasoned judgement. Do not: use appraise as a decorative synonym for describe. Example: appraise a proposal by examining cost, feasibility, access and long-term sustainability. Boundary: appraise and evaluate overlap strongly; appraise often carries a formal assessment sense. Cross-subject transfer: projects, source evaluation, business cases and essays. Check: is the judgement visibly tied to criteria rather than preference?

52. Assess

Core operation: judge extent, quality, importance, risk, performance or likely effect. Typical answer shape: define the dimension → examine evidence → weigh relevant factors → state judgement. Do not: stop at description. Example: assess the impact of a transport policy by examining travel time, access, cost and different user groups. Boundary: assessment is criteria-based judgement and may be narrower than a full evaluation depending the question. Cross-subject transfer: English, Science, Geography, Economics and project work. Check: what exact dimension are you assessing?

53. Critique

Core operation: examine strengths, weaknesses, assumptions, evidence and implications in a balanced, analytical way. Typical answer shape: what works → what does not → why → significance. Do not: treat critique as attack or fault-finding only. Example: critique a study by recognising its controlled design while questioning the representativeness of its sample. Boundary: critique includes positive judgement where deserved. Cross-subject transfer: research, literature, design and policy. Check: have you evaluated both strengths and limitations rather than simply criticised?

54. Evaluate

Core operation: judge quality, effectiveness, validity, importance or success against appropriate criteria. Typical answer shape: define criteria → examine evidence for each → consider limitations/alternatives → overall qualified judgement. Do not: give a list of features without deciding what they mean. Example: evaluate the effectiveness of a revision strategy by comparing improvement, time cost, transfer and sustainability. Boundary: exact mark-scheme expectations vary by discipline, but judgement is central. Cross-subject transfer: universal at higher levels. Check: where is the actual judgement, and what criteria justify it?

55. Judge

Core operation: reach a reasoned decision about quality, significance, correctness or relative strength. Typical answer shape: evidence → criteria → decision. Do not: substitute personal preference for reasoned judgement. Example: judge which source is more useful by comparing relevance, provenance, evidence and limitation. Boundary: judge is the general cognitive operation underlying assess and evaluate. Cross-subject transfer: source work, comparison, design and argument. Check: could another reader follow the path from evidence to your judgement?

56. Prioritise

Core operation: rank tasks, needs, causes or actions according to importance, urgency or another stated criterion. Typical answer shape: criteria → ranked items → explanation of order. Do not: call everything equally important. Example: prioritise revision by repairing high-frequency conceptual errors before rare low-impact mistakes. Boundary: prioritisation is a judgement under constraint. Cross-subject transfer: projects, policy, study planning and case studies. Check: why is item one ahead of item two?

57. Rank

Core operation: place items in an ordered sequence according to a specified dimension. Typical answer shape: ordered list + basis for ordering if required. Do not: rank without knowing the criterion. Example: rank three solutions by feasibility after considering cost, implementation time and resources. Boundary: rank tells order; prioritise usually implies action or attention should follow the ranking. Cross-subject transfer: evaluation, decision-making and data tasks. Check: is the same criterion used consistently across all items?

58. Recommend

Core operation: propose the option that should be chosen, based on evidence and criteria. Typical answer shape: options → evaluation → recommended option → justification → conditions/limitations. Do not: state a preference without reasons. Example: recommend the targeted intervention because it achieves comparable impact at lower cost while preserving access. Boundary: recommendation follows evaluation; it is not a substitute for it. Cross-subject transfer: case studies, reports, proposals and design tasks. Check: does the recommendation follow logically from the criteria?

59. Review

Core operation: examine material, performance or evidence systematically, often to summarise, evaluate and identify next steps. Typical answer shape: what happened → evidence → strengths/weaknesses → implications. Do not: assume review means summary only. Example: review the project by examining whether objectives were met, what constraints appeared and what should change next. Boundary: exact use varies widely: a literature review synthesizes research, while performance review evaluates results. Cross-subject transfer: research, projects and reflection. Check: what is the purpose of this review—summary, evaluation, synthesis or improvement?

60. Validate

Core operation: establish that a method, result, model or interpretation is sufficiently sound for a specified purpose. Typical answer shape: relevant standard → testing/checking → evidence → conclusion about validity. Do not: use validate to mean “agree with”. Example: validate a survey measure by checking whether it captures the construct it claims to measure. Boundary: validation is technical in many fields and may require specific procedures. Cross-subject transfer: Science, research, Mathematics models and data. Check: valid for what purpose and against what standard?

Part VII — Argument, defence and challenge verbs

61. Argue

Core operation: advance a defensible position using reasons, evidence and logical relationships. Typical answer shape: thesis → reasons → evidence → counterconsideration → conclusion. Do not: confuse argument with emotional disagreement. Example: argue that the policy should continue only under defined conditions. Boundary: an academic argument is structured support for a proposition. Cross-subject transfer: essays, presentations and source responses. Check: is the central claim supported, qualified and connected to evidence?

62. Assert

Core operation: state a proposition firmly. Typical answer shape: direct claim, ideally followed by support where the task requires it. Do not: assume firm wording makes the claim true. Example: “The writer asserts that economic growth justifies the environmental cost.” Boundary: assert describes the act and strength of statement; it does not imply evidence quality. Cross-subject transfer: source analysis, rhetoric and argumentative writing. Check: if you are the writer, what evidence makes the assertion defensible?

63. Challenge

Core operation: question the validity, strength, assumption or conclusion of a claim or method. Typical answer shape: target claim → reason for doubt → evidence/alternative. Do not: assume challenge equals refutation. Example: challenge the claim that the policy caused the change by identifying an uncontrolled variable. Boundary: challenge opens a claim to scrutiny; refute attempts to show it false. Cross-subject transfer: essays, source evaluation and scientific reasoning. Check: what specific part of the claim is being challenged?

64. Defend

Core operation: support a position against criticism by giving reasons and evidence. Typical answer shape: position → anticipated objection → response → evidence → qualified defence. Do not: repeat the position more loudly. Example: defend the choice of sampling method by explaining feasibility, coverage and limitations. Boundary: defence can acknowledge weaknesses while showing why the position remains reasonable. Cross-subject transfer: arguments, design decisions, methods and oral questioning. Check: have the strongest reasonable criticisms been answered?

65. Dispute

Core operation: contest a claim, interpretation or fact by presenting reasons for disagreement. Typical answer shape: disputed proposition → counter-evidence or reasoning → alternative. Do not: dispute without support. Example: dispute the claim that all observed improvement resulted from the intervention by pointing to a simultaneous policy change. Boundary: dispute signals disagreement but does not necessarily prove the opposing view. Cross-subject transfer: source analysis, essays and debate. Check: what evidence justifies the dispute?

66. Justify

Core operation: defend a choice, method, conclusion or answer by showing why it is reasonable. Typical answer shape: decision → relevant reason/evidence → explicit link showing why the reason warrants the decision. Do not: merely restate the choice. Example: justify selecting Option B by showing it meets the safety requirement at lower cost and with fewer implementation constraints. Boundary: justification is reason-giving; evaluation may compare broader strengths and weaknesses before the choice. Cross-subject transfer: Mathematics reasoning, Science methods, essays and design. Check: does each reason actually support the choice?

67. Qualify

Core operation: limit, refine or condition a statement so that it matches the evidence more precisely. Typical answer shape: original claim → condition/exception/degree → revised claim. Do not: treat qualification as weakness. Example: qualify “technology harms learning” into “frequent task-switching during learning can reduce sustained attention.” Boundary: qualification often strengthens accuracy by shrinking an overbroad claim. Cross-subject transfer: essays, conclusions, source interpretation and scientific reasoning. Check: where does the original claim stop being true?

68. Rebut

Core operation: answer an opposing claim with reasons or evidence showing why it is weak, incomplete or outweighed. Typical answer shape: represent opposition fairly → identify weakness → respond with evidence/reasoning. Do not: rebut a straw-man version of the opposing view. Example: rebut the cost objection by showing that initial expenditure is offset by lower maintenance costs over time. Boundary: rebut does not always mean prove false; it can mean answer effectively. Cross-subject transfer: essays, debates and source analysis. Check: did you answer the actual objection?

69. Refute

Core operation: show that a claim or argument is false, untenable or contradicted by decisive evidence/reasoning. Typical answer shape: claim → decisive counter-evidence/logical contradiction → conclusion that claim fails. Do not: use refute when evidence only raises doubt. Example: a direct record may refute a claim that no event occurred on that date. Boundary: refute is stronger than challenge or rebut and should be used cautiously. Cross-subject transfer: logic, source analysis and argument. Check: is the evidence genuinely strong enough to show the claim false?

70. Substantiate

Core operation: provide substantial support for a claim through evidence or reasoning. Typical answer shape: claim → relevant evidence → explanation of why the evidence supports it. Do not: use the word as a formal substitute for “say more”. Example: substantiate the claim that access improved by presenting before/after travel-time data across several groups. Boundary: substantiation strengthens support but may still fall short of proof. Cross-subject transfer: essays, reports and research. Check: is the support substantial, relevant and explained?

Part VIII — Synthesis and creation verbs

71. Combine

Core operation: bring separate elements together into one set, process or response. Typical answer shape: identify relevant components → join them appropriately → preserve necessary distinctions. Do not: assume combination automatically creates synthesis. Example: combine qualitative interview evidence with quantitative attendance data in one analysis. Boundary: combination puts things together; synthesis creates a coherent new understanding of their relationships. Cross-subject transfer: data, methods, writing and problem solving. Check: do the combined elements still make sense together?

72. Compose

Core operation: create a coherent text, response, representation or piece from selected components. Typical answer shape: planned structure → developed content → coherent finished product. Do not: treat composition as sentence accumulation. Example: compose a formal response that states the issue, evaluates options and recommends one course of action. Boundary: compose emphasises producing the finished whole. Cross-subject transfer: writing, music, visual representation and structured responses. Check: does every part contribute to the intended whole?

73. Develop

Core operation: expand an idea, argument, model or solution so it becomes more complete, functional or sophisticated. Typical answer shape: starting idea → added reasoning/evidence/detail → stronger form. Do not: mistake repetition for development. Example: develop an argument by adding evidence, counterargument and a qualified judgement. Boundary: development changes the intellectual state of the idea, not only its length. Cross-subject transfer: essays, designs, models and projects. Check: what new capability or understanding exists after development?

74. Design

Core operation: create a planned structure, method, experiment or solution that satisfies objectives and constraints. Typical answer shape: objective → requirements → choices → rationale → proposed system. Do not: present a random collection of features. Example: design an experiment that isolates the independent variable while controlling relevant conditions. Boundary: design requires intentional arrangement before implementation. Cross-subject transfer: Science, engineering, Mathematics, writing and projects. Check: can every design choice be linked to an objective or constraint?

75. Integrate

Core operation: combine ideas, sources, evidence or components so they function together within one coherent structure. Typical answer shape: multiple inputs → explicit relationships → unified response. Do not: place sources side by side without connection. Example: integrate evidence from two studies into one paragraph comparing why their results differ. Boundary: integration creates connection; synthesis may go further by generating a new understanding from those connections. Cross-subject transfer: research, writing, systems and interdisciplinary work. Check: are the inputs interacting, or merely coexisting?

76. Organise

Core operation: arrange information, ideas, evidence or steps into a structure that supports the task. Typical answer shape: choose an organising principle → group/sequence material → make relationships clear. Do not: assume chronological order is always best. Example: organise an essay by criteria rather than by source: effectiveness, feasibility, equity and sustainability. Boundary: organisation creates order; coherence requires that the ordered ideas make logical sense together. Cross-subject transfer: essays, notes, datasets, procedures and projects. Check: does the structure help the reader or solver see the reasoning?

77. Propose

Core operation: put forward an idea, explanation, solution, hypothesis or course of action for consideration. Typical answer shape: proposal → rationale → evidence/constraints → expected outcome. Do not: present a proposal as if it has already been proven effective. Example: propose a targeted transport subsidy and explain how it addresses a documented access barrier. Boundary: proposal creates a candidate solution; evaluation judges whether it is suitable. Cross-subject transfer: essays, design, research and case studies. Check: is the proposal specific enough to assess?

78. Synthesize

Core operation: combine multiple sources, ideas or findings into a new coherent understanding that shows relationships among them. Typical answer shape: identify shared question → connect agreements/differences → build integrated conclusion. Do not: write source A summary, then source B summary, then source C summary with no relationship. Example: synthesize three studies by explaining that each identifies a different mechanism influencing the same outcome. Boundary: synthesis is more than combination; it creates a higher-level structure. Cross-subject transfer: research, literature, Humanities and interdisciplinary tasks. Check: what new understanding exists because the sources were brought together?

79. Transform

Core operation: change information, a representation or a system substantially into another form while preserving or deliberately changing specified properties. Typical answer shape: starting form → transformation rule/process → new form → check. Do not: confuse superficial rewording with transformation. Example: transform data from a table into a graph, or transform a broad claim into a precise, testable question. Boundary: transformation implies meaningful structural change. Cross-subject transfer: Mathematics, data, writing and systems. Check: what changed, and what had to remain invariant?

80. Generate

Core operation: produce ideas, examples, data, possibilities or candidate solutions. Typical answer shape: several relevant outputs meeting stated constraints. Do not: treat generation as final evaluation. Example: generate three alternative explanations before deciding which is best supported. Boundary: generation increases the option set; selection and evaluation come later. Cross-subject transfer: brainstorming, hypotheses, design, examples and problem solving. Check: are the generated options distinct and relevant enough to be useful?

Part IX — Evidence, research and verification verbs

81. Cite

Core operation: refer explicitly to a source, example, authority or piece of evidence, usually with the required attribution convention. Typical answer shape: claim → cited evidence/source → explanation. Do not: cite without showing relevance. Example: cite a statistic from the original report, then explain how it supports the argument. Boundary: citation handles attribution; analysis explains significance. Cross-subject transfer: research, essays, source work and presentations. Check: is the source identifiable, relevant and represented accurately?

82. Corroborate

Core operation: provide independent evidence that supports or confirms another piece of evidence or claim. Typical answer shape: original evidence → independent source/observation → relationship. Do not: call repeated copies of the same original source independent corroboration. Example: attendance records corroborate interview reports that participation increased. Boundary: corroboration strengthens confidence but does not automatically prove the entire explanation. Cross-subject transfer: History, Science, journalism and research. Check: is the supporting evidence genuinely independent enough to add confidence?

83. Document

Core operation: create or preserve a systematic record of evidence, events, methods or changes. Typical answer shape: dated, organised, traceable record. Do not: rely on memory when the task requires a record. Example: document each change to the experimental procedure and the reason for it. Boundary: documentation records; interpretation explains. Cross-subject transfer: investigations, projects, research logs and process work. Check: could another person reconstruct what happened from the documentation?

84. Measure

Core operation: determine the amount, extent, magnitude or value of a variable using an appropriate method or scale. Typical answer shape: variable → instrument/metric → procedure → value. Do not: confuse the concept you care about with whatever is easiest to measure. Example: measure response time in seconds using the same procedure for each trial. Boundary: measurement quality depends on reliability and validity. Cross-subject transfer: Science, Mathematics, surveys and evaluation. Check: what exactly is being measured, and does the metric represent it adequately?

85. Observe

Core operation: notice and record what is directly seen, heard, measured or detected. Typical answer shape: objective observation separated from interpretation where relevant. Do not: present an inference as though it were directly observed. Example: observation: “The participant paused for six seconds”; interpretation: “The participant may have been uncertain.” Boundary: observation supplies evidence; inference assigns meaning. Cross-subject transfer: Science, behaviour, source analysis and practical tasks. Check: could another observer verify the observation independently?

86. Prove

Core operation: establish a proposition through a form of reasoning or evidence considered sufficient within the discipline. Typical answer shape: premises/definitions → valid steps → necessary conclusion, especially in Mathematics and logic. Do not: use prove casually in empirical subjects where evidence usually supports rather than establishes certainty. Example: prove a geometric relationship from accepted definitions and theorems. Boundary: “proof” has different standards across Mathematics, law, everyday speech and empirical Science. Cross-subject transfer: Mathematics, logic and argument. Check: what standard of proof does the discipline require?

87. Record

Core operation: write down or store observations, measurements, decisions or events accurately. Typical answer shape: structured entries with units, labels and dates where needed. Do not: alter the result to fit expectation. Example: record each temperature reading to the required precision. Boundary: recording captures data; analysis comes after. Cross-subject transfer: experiments, projects, logs and fieldwork. Check: is the record complete enough for later analysis and verification?

88. Test

Core operation: examine whether a hypothesis, claim, model, solution or component performs as expected under specified conditions. Typical answer shape: test condition → procedure → result → comparison with expectation. Do not: change several uncontrolled factors and claim one caused the result. Example: test whether the proposed algorithm handles edge cases correctly. Boundary: testing gathers evidence about performance or truth; one test rarely settles every condition. Cross-subject transfer: Science, Mathematics, design and software reasoning. Check: can the test actually discriminate success from failure?

89. Verify

Core operation: check whether information, identity, calculation, source or result is accurate or authentic. Typical answer shape: target → independent check → confirmation or correction. Do not: assume repetition without independent reference is verification. Example: verify a quotation against the original publication or verify a numerical result using a second method. Boundary: verification checks correctness/authenticity; validation may ask whether a method is appropriate for its intended purpose. Cross-subject transfer: research, Mathematics and data work. Check: what independent check supports the result?

90. Report

Core operation: communicate findings, events, observations or results accurately and in the expected format. Typical answer shape: relevant information → organised presentation → appropriate qualification. Do not: mix opinion into factual reporting unless the genre calls for evaluation. Example: report the findings by stating the measured trend, uncertainty and relevant limitation. Boundary: reporting communicates; interpretation and evaluation add further reasoning. Cross-subject transfer: Science, projects, journalism and formal writing. Check: is the report accurate, selective and fit for audience?

Part X — Higher-order response and decision verbs

91. Acknowledge

Core operation: recognise that a fact, limitation, objection or alternative exists. Typical answer shape: fair recognition → explanation of significance → response if needed. Do not: confuse acknowledgement with full agreement. Example: acknowledge that the policy increases cost before arguing that the access benefit justifies it. Boundary: acknowledgement is a balance move; concession grants more of the opposing point. Cross-subject transfer: essays, evaluation and source use. Check: has the relevant limitation or opposing consideration been represented fairly?

92. Anticipate

Core operation: predict a likely objection, consequence, need, difficulty or development before it occurs. Typical answer shape: current conditions → plausible future issue → reason → planned response if relevant. Do not: invent unlikely problems solely to look comprehensive. Example: anticipate that demand will rise after access improves and plan capacity accordingly. Boundary: anticipation is forward-looking reasoning based on evidence or patterns. Cross-subject transfer: planning, essays, systems and design. Check: is the anticipation grounded in the case?

93. Consider

Core operation: take a factor, perspective, possibility or consequence into account deliberately. Typical answer shape: identify relevant consideration → examine its effect on reasoning → integrate it into the conclusion. Do not: mention a factor and then ignore it. Example: consider long-term maintenance cost before recommending the cheaper initial option. Boundary: consider is broad; the surrounding task determines whether analysis, evaluation or discussion is needed. Cross-subject transfer: universal higher-order reasoning. Check: did the consideration actually change or inform the answer?

94. Conclude

Core operation: reach a final or provisional judgement based on preceding evidence and reasoning. Typical answer shape: evidence summary → judgement → qualification/conditions. Do not: introduce a new unsupported argument in the conclusion. Example: conclude that the pilot should continue, but only if a larger study confirms the effect. Boundary: conclusion strength must match evidence strength. Cross-subject transfer: essays, experiments, investigations and Mathematics reasoning. Check: could the conclusion be traced directly to the evidence presented?

95. Determine

Core operation: find, establish or decide a value, condition, relationship or answer using available information. Typical answer shape: relevant information → method/reasoning → determined result. Do not: guess when a method is available. Example: determine which variable most strongly predicts the outcome or determine the missing value from the equation. Boundary: determine can be computational or analytical depending subject. Cross-subject transfer: Mathematics, Science, data and case studies. Check: is the route to the determination explicit and valid?

96. Discuss

Core operation: examine an issue in a developed way, often considering relevant arguments, evidence, perspectives, implications or limitations. Typical answer shape: frame issue → develop relevant sides/considerations → weigh significance → reasoned conclusion if appropriate. Do not: produce a loose collection of opinions. Example: discuss whether online learning improves access by examining availability, digital barriers, flexibility, quality and different learner groups. Boundary: exact expectations vary significantly by subject and examination board. Cross-subject transfer: essays and extended responses. Check: has the issue been examined rather than merely described?

97. Explore

Core operation: investigate a question, idea or possibility openly enough to reveal patterns, alternatives or implications. Typical answer shape: several relevant avenues → evidence/examples → emerging insight. Do not: wander without a controlling question. Example: explore how setting shapes character behaviour by examining several scenes and their changing constraints. Boundary: exploration can be broader and less conclusion-driven than evaluation, though it still needs structure. Cross-subject transfer: essays, research and creative/analytical tasks. Check: is the exploration purposeful and evidence-based?

98. Predict

Core operation: state what is likely to happen based on patterns, models, theory or evidence. Typical answer shape: prediction → evidence/model → reasoning. Do not: present a guess without basis. Example: predict that demand will rise after price falls, assuming other relevant conditions remain stable. Boundary: prediction concerns future or unseen outcomes; explanation concerns mechanism. Cross-subject transfer: Science, Mathematics, Economics and reading. Check: what evidence or rule makes the prediction reasonable?

99. Respond

Core operation: produce an answer or action that addresses the prompt, source, objection or situation. Typical answer shape: identify what is being asked → select relevant operation → answer directly. Do not: write everything you know regardless of the question. Example: respond to a source by evaluating its usefulness rather than summarising its content if usefulness is the task. Boundary: respond is broad and must be unpacked using the specific prompt. Cross-subject transfer: universal. Check: does every major part of the response answer the actual question?

100. Select

Core operation: choose the most relevant item, method, evidence, option or answer from available possibilities. Typical answer shape: criterion → chosen item → brief justification where required. Do not: select by familiarity when the task supplies a more relevant criterion. Example: select the most appropriate evidence for a claim based on relevance and strength. Boundary: selection narrows possibilities; justification explains why the choice is defensible. Cross-subject transfer: multiple-choice reasoning, source use, design and problem solving. Check: what criterion made this option the right one?

The same topic under ten different command words

One of the fastest ways to understand academic verbs is to hold the topic constant and change only the command word. Consider the topic: school smartphone restrictions. The knowledge base can remain similar, but the answer operation changes.

Command	What the answer must do	Example opening
Define	state what a smartphone restriction is	A smartphone restriction is a rule limiting when or how students may use personal phones during school activities.
Describe	state features or what happens	Under the policy, phones remain stored during lessons and may be used during designated periods.
Explain	show why/how the restriction might affect learning	Restricting phones may improve sustained attention because it reduces notification-driven task switching.
Compare	relate two policy models on shared dimensions	A complete ban and a lesson-only restriction both reduce classroom use, but they differ in flexibility and enforcement burden.
Analyse	break the mechanism into parts and relationships	The policy changes attention by altering notification exposure, device availability and teacher enforcement.
Assess	judge a stated dimension such as impact	The policy’s impact is strongest where off-task phone use was previously frequent, but weaker where classroom routines were already stable.
Evaluate	judge overall quality/effectiveness against criteria	The policy is moderately effective at reducing visible distraction, but its overall value depends on enforceability, accessibility exceptions and whether learning outcomes improve.
Justify	defend a decision	A lesson-only restriction is preferable because it targets the main distraction period while preserving legitimate access outside lessons.
Discuss	examine relevant considerations and competing views	Smartphone restrictions can reduce distraction, but their value depends on enforcement, accessibility, student autonomy and the educational uses of devices.
Recommend	select an option after evaluation	Schools should adopt a lesson-only restriction with defined accessibility exceptions and a review after one term.

The factual topic is the same. What changes is the intellectual route. This is why students who revise only content can still underperform: they may know everything in the chapter but fail to convert that knowledge into the operation requested.

The command-word ladder: from retrieval to judgement

Academic verbs are not a perfect hierarchy—different disciplines use them differently—but a rough ladder helps students recognise increasing demands.

Level	Typical verbs	Main demand
1. Retrieve	name, recall, list, state	bring knowledge to mind accurately
2. Represent	define, describe, outline, label, summarise	present knowledge in an appropriate form
3. Relate	compare, contrast, classify, distinguish, sequence, relate	show relationships among items
4. Explain	explain, account, illustrate, demonstrate, clarify	show mechanism, meaning or reason
5. Analyse	analyse, examine, infer, interpret, diagnose, investigate	break down or derive meaning from evidence
6. Apply	apply, calculate, construct, derive, model, solve	use knowledge in a case or problem
7. Judge	assess, evaluate, critique, validate, recommend	use criteria to reach a judgement
8. Defend	argue, justify, rebut, refute, substantiate, qualify	build or challenge a defensible position
9. Integrate	integrate, synthesize, design, formulate, develop	create a coherent whole from components

A higher rung does not automatically mean a harder question. A difficult calculation may demand enormous expertise, while a poorly designed “evaluate” question can be shallow. The ladder is about the type of operation, not a universal measure of difficulty.

Wrong-mode answers: the hidden source of lost marks

A wrong-mode answer can be factually accurate and still miss the task. Diagnose the mode mismatch before diagnosing subject knowledge.

Describe asked, explain answered

Question: Describe the trend shown in the graph.
Wrong mode: “The value rises because demand increases.”
Better: “The value rises steadily from 20 to 35 between January and April, remains stable in May, then falls to 28 in June.”

The causal explanation may be correct, but the requested evidence is the observed trend. In a time-limited paper, unnecessary reasoning can consume time while failing to secure the descriptive marks.

Explain asked, describe answered

Question: Explain why the value falls after May.
Wrong mode: “The value falls from 35 to 28.”
Better: “The value falls because the temporary subsidy ends in May, increasing the effective price and reducing demand.”

The first answer restates the observation. The second supplies a mechanism linking cause and outcome.

Compare asked, two descriptions answered

Question: Compare Method A and Method B.
Weak: “Method A uses interviews. Method B uses surveys.”
Stronger: “Both methods gather self-reported information, but interviews provide greater depth while surveys can reach larger samples more efficiently.”

The stronger answer makes the shared dimension visible and expresses the relationship directly.

Analyse asked, features listed

Question: Analyse how the writer creates tension.
Weak: “The writer uses short sentences, repetition and darkness.”
Stronger: “The short sentences compress the pace, while repeated references to darkness reduce the reader’s access to information; together, these choices create uncertainty and make the approaching threat feel less predictable.”

Analysis needs relationships and function. The weak answer identifies techniques. The stronger answer explains how those techniques contribute to the effect.

Evaluate asked, advantages listed

Question: Evaluate the new system.
Weak: “It is faster, easier to use and popular.”
Stronger: “The system is effective at reducing processing time and is easy for most users, but its overall value is limited by high maintenance cost and poor accessibility for users who need screen readers. On balance, it is useful but requires accessibility repair before wider rollout.”

Evaluation requires judgement against criteria. Positive features alone do not create evaluation.

Justify asked, preference stated

Question: Justify your choice of Method B.
Weak: “I choose Method B because it is better.”
Stronger: “Method B is preferable because it measures the target variable directly, produces comparable numerical data and can be repeated under the same conditions.”

Justification makes the warrant explicit. “Better” is a conclusion without a reason.

Discuss asked, one-sided assertion answered

Question: Discuss whether online learning improves education.
Weak: “Online learning is good because students can study anywhere.”
Stronger: “Online learning can improve flexibility and extend access to specialised material, but its educational value depends on device access, learner independence, feedback quality and the nature of the task. It is therefore most effective as part of a system designed around learner needs rather than as a universal replacement for face-to-face teaching.”

Discussion requires developed examination of relevant considerations, not token “both sides” sentences.

24. Recommend asked; student picks an option immediately. Repair: evaluate first, then select.
25. Justify asked; student states preference. Repair: give reasons that warrant the choice.
26. Rebut asked; student repeats disagreement. Repair: answer the opposing reason directly.

30. Discuss asked; student gives unrelated opinions. Repair: organise relevant considerations around the question and conclude where appropriate.

A command-word diagnostic before revision

Give the student one topic they already know well and ask ten questions with different verbs. If factual knowledge stays constant while performance changes sharply across verbs, the weak link may be command-word execution rather than content knowledge.

Observed error	Likely weak link	Repair
accurate facts, no mechanism	describe/explain confusion	because/how chain drills
two accurate mini-essays, no relation	compare/contrast execution	dimension-by-dimension writing
techniques identified, effects not linked	analysis gap	feature → function → significance
many pros/cons, no verdict	evaluation gap	criteria + weighted judgement
choice stated, reason weak	justification gap	choice → criterion → evidence → warrant
sources summarized separately	synthesis gap	shared question + source relationships
certainty inflated	claim-strength gap	suggest/support/demonstrate/prove ladder
answer drifts from prompt	response control	verb + object rewrite before answering

How command words change across subjects

The verb may stay the same while the evidence changes. Students therefore need two layers of knowledge: the transferable operation and the disciplinary form it takes. “Analyse” always involves examining meaningful parts and relationships, but analysing a poem, a graph, a historical source and a mathematical proof are not the same performance.

Verb	English / Literature	Science	Mathematics	Humanities
Describe	state features of setting, tone or event	state observations or trend	describe pattern/shape/behaviour	state features of a place, event or source
Explain	show how language creates meaning/effect	give mechanism or reason	explain reasoning or relationship	show causal or conceptual relationship
Compare	relate texts/characters/techniques	compare methods/results	compare strategies or representations	compare sources, periods or systems
Analyse	feature → function → significance	variables, evidence, mechanism	structure of reasoning or data	source content, context, purpose, evidence
Interpret	derive meaning from text	explain meaning of result/graph	explain meaning of numerical/graphical result	derive meaning from source or pattern
Evaluate	judge interpretation/technique/argument	judge method, evidence or conclusion	judge reasonableness/efficiency/method	judge usefulness, reliability, policy or explanation
Justify	defend interpretation with text	defend method/choice with scientific reasons	defend method or result logically	defend judgement with evidence/criteria
Synthesize	integrate themes/sources/texts	combine findings into wider understanding	combine representations or results	integrate multiple sources/explanations

This table should not replace a subject-specific mark scheme. It shows the stable operation underneath disciplinary variation. A student who understands that operation is less likely to panic when the same verb appears in a new subject.

Maren’s laboratory — turning command words into essay architecture

Maren’s problem is not vocabulary meaning. She recognises analyse, evaluate, justify and discuss. Her weak link appears after the question is read: she begins writing before converting the verb into a structure.

Prompt 1: Analyse how the writer presents isolation

Maren’s first impulse is to collect techniques. She writes a plan:

• dark imagery;
• short sentences;
• first-person pronouns;
• empty setting.

The list is useful evidence selection, but not yet analysis. She rewrites the plan as a chain:

Feature: repeated empty-space imagery → function: removes social reference points → reader effect: makes the character’s environment feel unshared → significance: turns physical emptiness into a representation of emotional isolation.

Now the command word has altered the paragraph design. The technique is no longer the endpoint; it is the first step.

Prompt 2: Evaluate whether the policy is fair

Maren’s first draft says: “The policy helps many people, so it is fair.” That is a judgement, but the criterion is hidden. She converts evaluate into a four-part structure:

1. Define fairness criterion: access, burden and relevant differences in need.
2. Evidence for fairness: targeted support reaches groups facing documented barriers.
3. Evidence against fairness: eligibility rules exclude some households with similar need.
4. Judgement: fair in principle but incomplete in implementation.

The policy is broadly fair because it directs support toward households facing the strongest access barriers. However, the eligibility threshold creates abrupt exclusions for families just above the cutoff. On balance, the policy promotes equity more effectively than equal distribution would, but its fairness would improve if eligibility were graduated rather than binary.

The evaluation is visible because criteria, evidence and judgement are visible.

Prompt 3: Discuss whether examinations are a good measure of learning

Maren learns that discuss does not mean “write one paragraph for and one paragraph against”. She maps the issue by dimensions:

• reliability under standard conditions;
• coverage of knowledge and skills;
• performance under time pressure;
• transfer beyond examination format;
• practical need for scalable assessment;
• risk of narrowing learning to what is easily tested.

Her conclusion can then be conditional rather than binary: examinations measure some important forms of learning efficiently, but they are incomplete as a sole measure of capability. The command word has pushed her from opinion to structured consideration.

Iona’s laboratory — command words as reading instructions

Iona uses command words before returning to a passage. She rewrites each question into a retrieval target.

Question wording	Iona’s translation
Identify one reason	Find and name the reason.
Explain how the phrase creates tension	Find the phrase, then show mechanism from wording to effect.
Infer what the speaker feels	Find clues, then state the feeling those clues support.
Compare the speakers’ attitudes	Choose attitude dimensions and relate both speakers directly.
Evaluate the usefulness of the source	Judge usefulness for the stated enquiry using content, provenance and limitations.
Support your interpretation	Return to textual evidence that makes the reading defensible.

This translation prevents “hunt for a keyword” reading. The verb tells Iona what kind of evidence to retrieve and what she must do after finding it.

Inference example

“I suppose we could try,” Amir said, folding the timetable twice before placing it back on the desk.

Question: Infer Amir’s attitude toward the plan.

A weak answer says, “He is unsure.” A stronger inference shows the route: the phrase “I suppose” is tentative, while the repeated handling of the timetable suggests hesitation rather than enthusiasm. Therefore Amir appears uncertain and only cautiously willing to proceed.

The answer does not merely give a feeling word. It performs infer: clue → interpretation → supported conclusion.

Leonie’s laboratory — command words under examination time

Leonie’s risk is execution speed. She knows the verbs but occasionally writes the first thing she knows. Her solution is a ten-second command-word triage before writing:

1. Circle or mentally isolate the command verb.
2. Underline its object: evaluate what? compare which things?
3. Convert the verb into one action phrase: “judge against criteria”, “show mechanism”, “relate both directly”.
4. Estimate the number of distinct answer moves needed from marks or space.
5. Only then retrieve content.

Example: “Evaluate the reliability of the method.” Leonie’s internal translation is: judge consistency/dependability → use evidence from repeats/procedure → identify limitation → conclude. This takes seconds and stops her from writing a generic description of the method.

Cross-subject worked task 1 — Science

A student investigates whether light intensity affects the rate of photosynthesis. The same investigation can generate several different command-word questions.

1. Identify the independent variable. → Light intensity.
2. Describe the trend. → Rate increases as light intensity rises, then approaches a plateau.
3. Explain the trend. → Greater light intensity increases the rate while light is limiting; the plateau suggests another factor becomes limiting.
4. Interpret the plateau. → Additional light no longer produces a comparable increase, indicating that light is no longer the main limiting factor.
5. Evaluate the method. → Judge control of variables, repeatability, measurement precision and whether the proxy genuinely reflects photosynthesis rate.
6. Justify one improvement. → Repeat each condition because multiple measurements reduce the influence of random variation and allow a more reliable mean.

The content base overlaps, but each verb extracts a different operation from it.

Cross-subject worked task 2 — Mathematics

Suppose a problem presents two methods for estimating the area under a curve.

1. Calculate the estimate using Method A. → Perform the specified numerical procedure.
2. Compare the two estimates. → State relative size, difference and perhaps closeness to a benchmark.
3. Explain why Method B is more accurate. → Link its smaller interval width or better representation to reduced approximation error.
4. Justify which method you would use under a time constraint. → Balance accuracy and computational cost.
5. Evaluate the approximation. → Judge reasonableness using bounds, known behaviour or comparison with a more accurate method.
6. Determine the number of intervals needed to meet a stated tolerance. → Use the relevant relationship and solve for the required condition.

Again, the command word routes the mathematical knowledge into a different response.

Cross-subject worked task 3 — History / source work

Imagine a newspaper editorial written during a political reform campaign.

1. Identify the writer’s main claim. → Name the proposition.
2. Describe the tone. → State relevant tonal features with brief evidence.
3. Infer the intended audience. → Use language, assumptions and publication context as clues.
4. Analyse how the writer persuades. → Examine rhetoric, evidence, framing and omissions.
5. Evaluate usefulness for an enquiry. → Judge what the source can reveal, considering content, provenance and limitations.
6. Corroborate the source. → Find independent evidence supporting or challenging its factual claims.

A source can be highly useful without being neutral. Evaluation should not collapse into “biased = useless”. The verb invites judgement of usefulness for a specific enquiry.

Cross-subject worked task 4 — English argumentative writing

Topic: Should public transport be free for students?

1. Define the policy scope: all journeys, school journeys, or a capped subsidy?
2. Explain the access mechanism: how would fares affect participation in school or activities?
3. Analyse trade-offs: cost, capacity, equity, incentives and administrative simplicity.
4. Evaluate alternatives: universal free travel versus targeted subsidy.
5. Justify the recommended design with criteria.
6. Qualify the conclusion by stating conditions such as peak capacity or eligibility evidence.

The verbs can become an essay-planning checklist. Instead of searching for “advanced vocabulary”, the student builds an answer using academic operations.

Command-word pairs that students should never collapse

Pair	Difference to protect
describe / explain	what is observed versus why/how it happens
identify / analyse	name the feature versus explain its role/relationship
compare / contrast	relationship including similarities/differences versus foreground difference
analyse / evaluate	examine structure/function versus judge quality/value
assess / justify	judge a dimension versus defend a specific choice/conclusion
challenge / refute	raise doubt versus show false
rebut / refute	answer opposition versus demonstrate falsity
summarise / synthesize	compress one body of material versus integrate several into new understanding
verify / validate	check correctness/authenticity versus establish fitness/soundness for purpose
observe / infer	directly detect versus derive meaning from clues
calculate / interpret	produce numerical result versus explain its meaning
recommend / propose	select after judgement versus put forward for consideration

Many examination errors happen because students treat nearby verbs as synonyms. Learning the boundary between them is often more valuable than learning another hundred isolated definitions.

Worksheet A — Match the command word to the answer operation

For each task description, choose the academic verb that best matches the operation. More than one verb can sometimes work in ordinary language, but the answer key selects the most precise verb from this article.

1. State the essential meaning of a concept and its boundary. → Define.

38. Make a reasoned position with evidence. → Argue.
39. Provide substantial evidence for a claim. → Substantiate.
40. Question the strength or validity of a proposition. → Challenge.

Worksheet B — Which answer mode does the question require?

Read each question. Before answering the content, identify the response mode. This drill trains the habit of converting the command word into a procedure.

1. Describe the change in population from 2000 to 2020. → Mode: pattern/features. Give what changed, when and by how much if data permit.
2. Explain the change in population. → Mode: reason/mechanism. Link causes to the observed change.
3. Analyse how migration affected the city. → Mode: parts/relationships. Show mechanisms across housing, labour, services or demographics.
4. Evaluate the city’s response. → Mode: criteria + evidence + judgement.
5. Justify one policy choice. → Mode: choice + reason + evidence + warrant.
6. Compare two sources. → Mode: shared dimensions + relational statements.
7. Infer the speaker’s attitude. → Mode: clues + interpretation.
8. Interpret the graph. → Mode: meaning/significance, not merely raw description.
9. Assess the reliability of the method. → Mode: judge consistency/dependability with evidence.
10. Critique the study. → Mode: strengths + weaknesses + assumptions + implications.
11. Discuss whether the reform should continue. → Mode: relevant competing considerations + reasoned conclusion.
12. Synthesize the three sources. → Mode: connect sources around a shared question and build new understanding.
13. Outline the procedure. → Mode: main stages only.
14. Trace the development of the conflict. → Mode: origin → key stages → outcome.
15. Recommend a strategy. → Mode: evaluate options → select → justify.
16. Propose an investigation. → Mode: put forward a workable method with rationale.
17. Determine the missing value. → Mode: use available information and reasoning to find it.
18. Demonstrate that the relationship holds. → Mode: show clearly through proof, evidence or valid working.
19. Corroborate the source. → Mode: find independent evidence that supports or challenges its factual claims.
20. Acknowledge one limitation. → Mode: recognise the boundary fairly and explain its significance if required.

Worksheet C — Turn the command word into an answer plan

For each question, write a four-step plan before drafting the answer. Suggested plans are given below so students can compare their routing logic.

1. Evaluate whether remote learning improves educational access.

1. Define criteria for access: availability, affordability, usability and participation.
2. Present evidence of benefits: location flexibility, specialist resources, scheduling.
3. Present limitations: devices, internet, self-management, accessibility needs.
4. Reach a qualified judgement about when remote learning improves access.

2. Analyse how the writer presents fear.

1. Select a feature such as syntax, imagery or viewpoint.
2. Explain how the feature operates.
3. Connect the feature to reader experience or character perspective.
4. Explain how the parts together build the larger presentation of fear.

3. Justify using Method B rather than Method A.

1. Name the selection criterion.
2. Show how Method B performs on that criterion.
3. Compare the relevant weakness of Method A.
4. State why this difference warrants choosing B.

4. Discuss whether examinations are fair.

1. Define what fairness could mean: equal conditions, comparable standards, opportunity to demonstrate learning.
2. Consider reasons examinations can be fair: standardised conditions, common criteria.
3. Consider limitations: unequal preparation, performance anxiety, narrow measurement.
4. Reach a reasoned, possibly conditional conclusion.

5. Compare two explanations for declining participation.

1. Choose shared dimensions such as mechanism, evidence, scope and assumptions.
2. Compare both explanations on mechanism.
3. Compare evidence strength and limitations.
4. State the most important similarity/difference if required.

6. Infer why the character avoids the doorway.

1. Locate behavioural or language clues.
2. State a plausible reason or feeling.
3. Connect each clue to the inference.
4. Avoid claiming more than the text supports.

7. Critique the survey design.

1. Identify a strength in sampling, question design or consistency.
2. Identify a weakness or bias.
3. Explain how each affects what can be concluded.
4. Suggest improvement if the task allows.

8. Synthesize the sources on urban transport.

1. Identify the shared question across all sources.
2. Group sources by agreement, disagreement or different mechanisms.
3. Integrate evidence within themes rather than source-by-source summary.
4. Build a combined conclusion that none of the sources provides alone.

Worksheet D — Claim-strength verbs

Choose the safest verb based on the evidence described. This is especially important because a command-word article should also teach students not to misuse academic verbs in their own writing.

1. A small observational study finds two variables move together. Safest: suggests / indicates an association, not proves causation.
2. A replicated controlled experiment consistently produces the predicted effect. Safer: demonstrates the effect under tested conditions, though generalisation may still need qualification.
3. An original record shows an event happened, contradicting a claim that it never occurred. The record may refute that specific factual claim.
4. A second independent source matches the first source’s factual detail. It corroborates the evidence.
5. A writer offers one reason against a policy. The reason challenges the policy; it does not automatically refute it.
6. A student gives several relevant data points supporting a proposition. The evidence substantiates or supports the claim depending strength.
7. A conclusion is revised from “all students” to “many students in the sample”. The writer qualifies the claim.
8. A mathematical argument derives a result necessarily from accepted premises. It may prove the result within that system.
9. A measuring instrument is checked against a known reference value. The researcher verifies the reading.
10. A survey instrument is tested to see whether it really measures the intended construct. The researcher validates the instrument.

Worksheet E — Command-word sorting

Sort the following verbs into the most useful operation family. Some verbs can serve more than one purpose; the exercise is about identifying the dominant role in this article.

• Recall/representation: define, describe, identify, label, list, name, outline, recall, state, summarise.
• Explanation: account, clarify, demonstrate, elaborate, exemplify, explain, illustrate, paraphrase, restate, translate.
• Relationship: categorise, classify, compare, connect, contrast, differentiate, distinguish, group, relate, sequence.
• Analysis: analyse, annotate, deconstruct, detect, diagnose, examine, infer, interpret, investigate, trace.
• Application: adapt, apply, calculate, construct, derive, estimate, formulate, model, solve, use.
• Evaluation: appraise, assess, critique, evaluate, judge, prioritise, rank, recommend, review, validate.
• Argument: argue, assert, challenge, defend, dispute, justify, qualify, rebut, refute, substantiate.
• Synthesis/creation: combine, compose, develop, design, integrate, organise, propose, synthesize, transform, generate.
• Evidence/research: cite, corroborate, document, measure, observe, prove, record, test, verify, report.
• Higher-order response: acknowledge, anticipate, consider, conclude, determine, discuss, explore, predict, respond, select.

From question to procedure: ten complete examples

These examples show how a student can translate a question into a mini-procedure before writing.

1. “Analyse the writer’s use of contrast.” → locate contrasts → explain what is being opposed → show how opposition shapes meaning → explain significance to the passage.
2. “Evaluate the reliability of the results.” → define reliability → inspect repeats/consistency → identify sources of variation → judge confidence.
3. “Compare the two economic policies.” → choose shared dimensions → analyse both on each dimension → state similarities/differences → identify most important relationship if required.
4. “Explain why the reaction slows.” → state relevant mechanism → connect changing condition to collision/reaction process → link to slower rate.
5. “Justify the use of median.” → identify distribution/outliers → explain median’s resistance to extreme values → connect property to dataset.
6. “Discuss whether tourism benefits the region.” → define benefit dimensions → economic gains → social/environmental costs → distribution of benefits → qualified overall view.
7. “Infer the narrator’s attitude.” → identify wording/tone clues → state attitude → explain evidence → avoid overclaiming.
8. “Critique the experimental design.” → strength → weakness → effect on validity/reliability → improvement.
9. “Synthesize Sources A–C.” → shared question → agreements → differences → explanation for differences → combined insight.
10. “Recommend one option.” → define criteria → compare options → choose best fit → justify → state conditions.

A 30-day academic-verb mastery programme

Teacher deployment — a 12-lesson sequence

Lesson	Focus	Core activity
1	diagnostic	Same topic, ten command words; identify mode errors.
2	describe vs explain	Graph/source pairs; “what” versus “why/how”.
3	compare/contrast/distinguish	Dimension-by-dimension response writing.
4	analyse	Feature → function → relationship → significance.
5	infer/interpret	Clue → meaning → evidence justification.
6	apply/construct/derive	Use concepts rather than restating them.
7	assess/evaluate	Criteria → evidence → judgement.
8	justify/qualify	Choice → reason → warrant; broad claim → precise claim.
9	challenge/rebut/refute	Strength ladder for disagreement.
10	summarise/integrate/synthesize	One source versus several sources.
11	cross-subject transfer	Same verb in English, Science, Math and Humanities.
12	timed execution	Command-word triage followed by mixed assessment.

The teacher should record error type, not merely score. A student who gives accurate content under the wrong command word needs different repair from a student who misunderstands the content. Useful labels include K knowledge, M mode, E evidence, J judgement, S scope and T transfer.

Teacher marking shorthand for command-word errors

Code	Meaning	Example	Repair
M-D/E	describe/explain confusion	repeats trend when cause is required	add explicit mechanism chain
M-C	comparison missing	two separate descriptions	shared dimensions + relational language
M-A	analysis missing	feature spotting only	feature → function → significance
M-EV	evaluation missing	pros/cons without verdict	criteria + weighted judgement
M-J	justification missing	choice without warrant	criterion + evidence + why it supports choice
M-SY	synthesis missing	source-by-source summaries	organise by shared question/themes
S	scope error	all students from one sample	qualify population/condition
C	claim strength	proves from weak evidence	use suggest/support/indicate

Parent use — five-minute command-word conversations

Parents do not need to teach examination terminology in a technical way. They can ask one topic through several verbs. Choose something familiar—school lunch, transport, screen time, recycling, exercise—and vary the instruction.

1. Describe the current situation.
2. Explain why it happens.
3. Compare two possible solutions.
4. Evaluate which solution works better.
5. Justify the option you would choose.

The conversation exposes whether the child changes mode. If every answer sounds like description, the problem is visible without a worksheet. If the child can explain but not evaluate, the next step is criteria and judgement rather than more factual revision.

Frequently asked questions

What are command words?

Command words are verbs or directive phrases in questions that tell students what operation the response should perform. Examples include describe, explain, compare, analyse, evaluate and justify. Their exact assessment meaning can vary by subject or examination system, so students should combine general understanding with their own syllabus guidance.

What is the difference between an academic verb and a command word?

An academic verb describes an intellectual action used in learning, reasoning or writing. A command word is an instruction in a task or question. Many words can function as both. Analyse is an academic verb in “students analyse evidence” and a command word in “Analyse the evidence.”

Do command words have exactly the same meaning in every subject?

No. The underlying operation may be similar, but disciplinary evidence and mark-scheme expectations differ. “Evaluate” in Science may focus on method, reliability and validity; in an essay it may involve broader criteria, competing considerations and a reasoned judgement. Always check the subject-specific guidance.

What is the difference between describe and explain?

Describe states relevant features or what happens. Explain shows why or how it happens. “The line falls after June” is description. “The line falls because the subsidy ends, raising the effective price” is explanation.

What is the difference between analyse and evaluate?

Analyse examines parts, relationships and functions. Evaluate judges quality, effectiveness or significance against criteria. Analysis may reveal how a method works; evaluation decides how good or suitable it is.

What is the difference between compare and contrast?

In general academic use, compare examines items on shared dimensions and can include similarities and differences. Contrast foregrounds difference. Some examination systems define their commands more specifically, so students should follow local guidance.

What is the difference between justify and explain?

Explain shows why or how something happens. Justify gives reasons showing why a choice, method or conclusion is reasonable. Explanation is mechanism-oriented; justification is defence-oriented.

What is the difference between assess and evaluate?

They overlap. Both involve judgement. Assess often focuses on a stated dimension such as impact, extent, risk or reliability. Evaluate often suggests a broader judgement of quality, effectiveness or value against criteria. Exact usage varies by syllabus.

What is the difference between rebut and refute?

Rebut means answer an opposing argument effectively. Refute is stronger: show that a claim is false or untenable. If your evidence merely raises doubt, challenge or rebut may be safer than refute.

What is the difference between summarise and synthesize?

Summarise compresses the essential content of material. Synthesize combines multiple ideas or sources into a new coherent understanding. A synthesis should show relationships across sources rather than present separate summaries.

How can students remember command words?

Memorise a short operation phrase rather than a long definition: describe = what; explain = why/how; compare = relate both; analyse = parts + relationships; evaluate = criteria + judgement; justify = defend with reasons; infer = clues → conclusion; synthesize = sources → new whole. Then practise with new topics.

Why do students still answer the wrong mode after learning definitions?

Recognition is easier than execution. A student may know that evaluate means judge but still begin writing descriptive facts under time pressure. Practice must therefore include verb-to-procedure retrieval and timed transfer, not only matching definitions.

Should students memorise answer templates?

Short procedural templates can help, but rigid sentence formulas should not replace thinking. “Criteria → evidence → judgement” is a useful evaluation route. A fixed paragraph copied into every subject is not. The procedure should adapt to the evidence and discipline.

How do command words help time management?

They stop students from doing unnecessary operations. A “state” question may need a direct sentence, while an “evaluate” question needs evidence and judgement. Matching answer depth to the verb and marks reduces both under-answering and over-answering.

Can one question contain more than one command word?

Yes. A task may ask students to describe and explain, compare and evaluate, or analyse and justify. Treat each command as a required operation. A response that completes only one may be incomplete even if that part is strong.

A practical command-word card

Verb	Fast internal translation
Define	Give the meaning/boundary.
Describe	What is there / what happens?
Explain	Why/how?
Compare	Relate both on shared dimensions.
Contrast	Show meaningful differences.
Infer	Clues → supported conclusion.
Interpret	What does it mean?
Analyse	Parts → relationships → significance.
Assess	Judge this dimension.
Evaluate	Criteria → evidence → judgement.
Justify	Defend the choice with reasons.
Discuss	Examine relevant considerations.
Qualify	Make the claim more precise.
Synthesize	Sources → relationships → new whole.
Recommend	Evaluate → choose → justify.

The card is deliberately short. In an examination, a student needs a routing instruction, not a dictionary paragraph.

Final unseen mixed assessment — 60 command-word questions

This final assessment deliberately mixes recall, explanation, analysis, application, evaluation, argument and synthesis. The first task is always the same: identify the verb, translate it into an operation, then answer the content.

1. Define validity. Answer mode: state the boundary of the concept. Example: validity concerns whether a method, measure or inference is appropriate for what it claims to measure or establish.
2. Describe a graph that rises slowly, plateaus, then falls sharply. Answer mode: report those features accurately without inventing causes.
3. Identify the dependent variable in an experiment. Answer mode: name the measured outcome.
4. Outline the stages of a source-based investigation. Answer mode: main steps only—question, source collection, evaluation, analysis, conclusion.
5. Summarise a report. Answer mode: compress the central claim, main evidence and important qualification.
6. Explain why a metal wire’s resistance may rise with temperature. Answer mode: give the relevant physical mechanism, not only the trend.
7. Illustrate opportunity cost. Answer mode: provide a clear case showing the value of the next-best alternative forgone.
8. Paraphrase “The evidence may indicate a relationship.” Answer mode: preserve uncertainty, for example “The evidence could suggest that the variables are related.”
9. Compare two revision methods. Answer mode: choose shared dimensions such as retrieval demand, time cost and delayed retention, then relate both methods directly.
10. Contrast explicit and implicit meaning. Answer mode: foreground direct statement versus meaning that must be inferred.
11. Distinguish accuracy from precision. Answer mode: accuracy concerns closeness to the correct value; precision concerns exactness or consistency of measurement.
12. Sequence the stages of an experiment. Answer mode: place planning, measurement, analysis, evaluation and conclusion in the appropriate order.
13. Analyse how repetition affects a speech. Answer mode: identify the repeated element, explain its function, connect it to emphasis/rhythm/audience effect, and state significance.

Model answer audit 1 — “Evaluate”

Question: Evaluate whether a city should make buses free for students.

Free bus travel could improve educational access by removing a direct transport cost, especially for students who travel long distances or attend activities outside normal school hours. However, effectiveness should be judged against more than ridership. A universal free-fare policy may subsidise many journeys that would have occurred anyway, while increasing operating costs and capacity pressure. A targeted subsidy could produce a similar access benefit at lower cost, although it would require eligibility rules and administration. On balance, free travel is most defensible where fares are a documented barrier, but a targeted model is likely to be more financially sustainable than a universal scheme.

Why it answers evaluate: it uses criteria—access, effectiveness, cost, capacity, sustainability—rather than listing advantages. It considers an alternative and ends with a qualified judgement. Remove the final judgement and it becomes analysis without full evaluation.

Model answer audit 2 — “Analyse”

Question: Analyse how the writer creates a sense of uncertainty.

The writer creates uncertainty by restricting what both the character and reader can know. Repeated references to “something” moving beyond the window avoid naming the threat, while the short question “Again?” suggests that the character recognises a pattern but cannot explain it. The first-person viewpoint further narrows access to information because the reader receives only the character’s incomplete perception. Together, vague reference, fragmented syntax and limited viewpoint make the threat feel present but undefined, which sustains uncertainty.

Why it answers analyse: it does not merely identify “vague words, short sentence, first person”. It explains function and relationship: all three reduce information and jointly produce the effect.

Model answer audit 3 — “Justify”

Question: Justify using a representative sample rather than interviewing only volunteers.

A representative sample is preferable because the research question concerns the wider student population. Interviewing only volunteers risks over-representing students with unusually strong opinions or greater willingness to participate. A sample designed to reflect relevant population characteristics therefore provides a more defensible basis for generalisation, even though no sample can remove every source of bias.

Why it answers justify: the choice is explicit, the criterion is generalisability, the weakness of the alternative is explained, and the reason is linked back to the choice.

Model answer audit 4 — “Discuss”

Question: Discuss whether artificial intelligence should be used in school assignments.

Artificial intelligence can support school assignments when it helps students generate questions, receive feedback or clarify difficult language, because these uses can increase access to explanation without necessarily replacing the student’s reasoning. The same technology can weaken learning if students outsource planning, analysis or final writing before those capabilities are secure. A blanket ban would therefore remove legitimate support, while unrestricted use could make assessment evidence less trustworthy. A more workable approach is to define permitted assistance by task: students might use AI for feedback or brainstorming while remaining responsible for the reasoning and final submitted work. Whether AI should be used is thus less important than how its role is bounded, disclosed and matched to the learning objective.

Why it answers discuss: the response examines benefits, risks, assessment implications and an alternative policy model before reaching a nuanced position. It does not perform a superficial “one paragraph yes / one paragraph no” routine.

The final mastery rule

A command word is mastered when the student can do four things without notes: explain its core operation, distinguish it from its nearest neighbour, convert it into an answer structure, and execute that structure on an unfamiliar topic.

Knowing that evaluate means “judge” is recognition. Looking at a new question, choosing relevant criteria, weighing evidence and reaching a qualified judgement is control.

Knowing that analyse means “break down” is recognition. Finding the meaningful parts, explaining their relationships and showing why those relationships matter is control.

Knowing that justify means “give reasons” is recognition. Selecting the relevant criterion, connecting evidence to the choice and explaining why that evidence warrants the decision is control.

That is the purpose of the Top 100: not to make students memorise a hundred verbs, but to give them a hundred routes for turning knowledge into an answer.

Read the verb. Translate the operation. Build the answer the question is actually asking for.

Answer-frame bank — turn the verb into a usable sentence route

These are not scripts to memorise word for word. They are structural prompts. Replace the placeholders with the actual content and adjust them to the subject, evidence and mark scheme.

Define

Frame: “X is ______, characterised by ______ and distinguished from Y by ______.” Use this when the concept needs a boundary, not merely an example. A good definition often names the class of thing first, then the feature that separates it from nearby concepts.

Describe

Frame: “From A to B, ______ increases/decreases/remains stable, while ______.” Keep the answer tied to observable features. If the task asks for a visual, trend or process description, avoid explaining causes unless the question adds a second verb.

Explain

Frame: “This happens because ______, which causes/leads to ______; therefore ______.” The middle link is the important part. If the answer can remove “because/how” and still say the same thing, the response may still be description rather than explanation.

Compare

Frame: “Both A and B ______, but A ______ whereas B ______.” Then repeat on another shared dimension. Direct relational language is usually stronger than separate paragraphs that force the examiner to perform the comparison mentally.

Contrast

Frame: “A differs from B primarily in ______: A ______, while B ______.” Choose differences that matter to the question. A contrast answer improves when the student states the dimension of difference instead of producing unrelated facts.

Differentiate / Distinguish

Frame: “X refers to ______, whereas Y refers to ______; the key distinction is ______.” This works well for pairs such as reliability/validity, effectiveness/efficiency, accuracy/precision, correlation/causation and explicit/implicit meaning.

Infer

Frame: “The evidence suggests ______ because ______ and ______.” The conclusion should be no stronger than the clues. If the source supports several plausible readings, state the one best supported rather than pretending inference creates certainty.

Interpret

Frame: “The pattern/phrase/result can be interpreted as ______ because ______; however, ______ limits certainty.” Interpretation gives meaning to evidence. Adding a limitation often protects against overreading, especially in data and source questions.

Analyse

Frame: “The feature ______ functions by ______, which affects/relates to ______; together this contributes to ______.” The route is part → function → relationship → significance. The exact language changes by subject, but the logic remains useful.

Assess

Frame: “The impact/reliability/extent is ______ because ______, although ______ limits the judgement.” Assess usually needs a stated dimension. Name that dimension early so the paragraph does not drift into generic evaluation.

Evaluate

Frame: “Against the criteria of A, B and C, the option performs ______. Evidence ______ supports this, while ______ is a limitation. Overall, ______.” The criteria are the engine. Without them, the paragraph risks becoming a list of opinions.

Critique

Frame: “A strength is ______ because ______. However, a limitation is ______, which matters because ______. Therefore the conclusion/method is ______.” Critique is not synonymous with criticism; a balanced answer makes strengths visible too.

Justify

Frame: “Option X is preferable because ______. This matters because ______, and evidence ______ shows ______.” The second “because” is often where justification becomes real: it explains why the reason is relevant to the choice.

Recommend

Frame: “I recommend X because it best satisfies ______ and ______. Compared with Y, it ______. This recommendation depends on ______.” A recommendation should feel like the endpoint of evaluation, not a preference stated before the analysis begins.

Discuss

Frame: “The issue depends on ______, ______ and ______. On one hand, ______; however, ______. A more complete judgement is ______.” Do not force artificial symmetry. Give each consideration weight according to evidence and relevance.

Qualify

Frame: “The claim is accurate only when ______ / for ______ / under ______.” Qualification adds boundaries of population, condition, degree, time or evidence. This is one of the most powerful ways to turn an overstatement into a defensible academic claim.

Challenge

Frame: “The claim can be challenged because ______; an alternative explanation is ______.” Challenging opens the proposition to doubt. Do not jump to “therefore false” unless the counter-evidence is strong enough to support refutation.

Rebut

Frame: “Although the objection that ______ is valid to an extent, it is outweighed/limited by ______ because ______.” Strong rebuttal represents the objection accurately before responding. A distorted objection produces a weak answer even if the rebuttal sounds confident.

Refute

Frame: “The claim that ______ is contradicted by ______, which directly shows ______.” Use this only when the evidence can genuinely establish falsity. If it merely introduces doubt, choose challenge or rebut.

Substantiate

Frame: “The claim is substantiated by ______ and ______ because these show ______.” Multiple evidence sources do not automatically substantiate a claim; they must be relevant, credible and linked to the proposition.

Synthesize

Frame: “Across the sources, a common pattern is ______. Source A emphasises ______, while Source B explains ______; together they suggest ______.” Synthesis is organised around relationships, not around source order.

Verify

Frame: “The information was verified by checking ______ against ______.” Verification requires a reference or independent method. Repeating the same process without a meaningful check may reproduce the same error.

Validate

Frame: “The method/model is valid for ______ because ______, although it is limited when ______.” Validity is always validity for a purpose, construct or inference. State the target rather than calling something simply “valid”.

Conclude

Frame: “Taken together, the evidence supports the conclusion that ______, although ______.” A conclusion should compress the reasoning already established. It should not introduce a completely new argument at the final moment.

Delayed transfer drill — twenty unfamiliar topics

Use the verb shown to produce a one-sentence plan. The topic is deliberately unfamiliar enough that students must rely on operation knowledge rather than memorised model answers.

1. Analyse how a museum exhibition guides visitor attention. → Identify design features, explain how they shape movement/focus, connect to visitor interpretation.
2. Evaluate whether a city should introduce night buses. → Set criteria such as demand, access, cost and safety; weigh evidence; judge.
3. Justify using a smaller but more representative sample. → Link representativeness to the research population and explain why relevance outweighs raw size.
4. Compare two renewable-energy sources. → Use shared dimensions such as reliability, cost, emissions and location constraints.
5. Infer why a customer abandons an online form. → Use clues such as repeated errors, time spent and exit point to support a cautious conclusion.
6. Discuss whether public parks improve urban life. → Examine health, social, environmental, land-use and distribution considerations.
7. Critique a school survey about homework. → Strength, sampling issue, wording issue, implications for conclusion.
8. Synthesize three articles on sleep. → Organise by shared mechanisms or disagreements and build a combined conclusion.
9. Explain why a queue grows even when service continues. → Link arrival rate and service rate; show mechanism.
10. Assess the impact of removing late fees at a library. → Judge borrowing, returns, access, replacement loss and affected groups.
11. Recommend one of three emergency-notification systems. → Define reliability, speed, reach and cost; compare; select; qualify.
12. Interpret a plateau in sales after rapid growth. → Explain plausible saturation or constraint while noting alternative explanations.
13. Diagnose why an automated process fails only at peak times. → Use timing pattern to investigate capacity, concurrency or resource bottlenecks.
14. Qualify “remote work increases productivity”. → Narrow by task type, team structure, measurement period or worker context.
15. Refute the claim that an event never occurred when a verified record documents it. → Present the record and show the direct contradiction.
16. Validate a new reading test. → Show evidence that scores correspond to the reading ability the test claims to measure.
17. Trace the spread of a technological standard. → Origin, early adoption, institutional support, wider diffusion, current form.
18. Design a fair comparison between two learning apps. → Same learners/conditions, defined outcomes, controlled exposure, consistent measures.
19. Corroborate an eyewitness account. → Seek independent records, images, logs or other accounts not derived from the same source.
20. Select the strongest evidence for a claim. → Use relevance, credibility, representativeness and directness as criteria.

A final performance rubric

Dimension	0	1	2
Verb recognition	misreads verb	recognises broadly	translates precisely
Answer mode	wrong operation	partly matches	fully matches command
Evidence selection	irrelevant	mixed	targeted to operation
Reasoning structure	disconnected	partly organised	clear procedure
Claim strength	over/underclaims	some calibration	matches evidence
Transfer	works only on memorised examples	works with support	works on unfamiliar topics

A student who scores well on factual knowledge but poorly on answer mode does not need another content chapter first. The first weak link is routing. Repair the routing, then retest the same knowledge under a different command word.

The final distinction

Academic verbs are vocabulary, but they are also procedures.

Explain is a word and a mechanism-building instruction.

Analyse is a word and a relationship-finding instruction.

Evaluate is a word and a criteria-based judgement instruction.

Justify is a word and a reason-defence instruction.

Synthesize is a word and a source-integration instruction.

When the verb becomes a procedure, the student no longer has to guess what a question wants.

The verb is the doorway. The answer structure is the route through it.

Rapid reference — the ten command-word pairs most likely to be confused

This final reference is designed for the last stage of revision. Each pair looks similar enough to create mistakes under pressure, but the answer operation is different.

Describe vs Explain

Describe asks what is present, what happens, or what pattern is visible. Explain asks why or how it happens. If the answer contains only “the line falls”, it describes. If it adds the mechanism causing the fall, it explains. A fast check is to ask whether the response contains an actual causal, functional or logical link rather than a restatement.

Compare vs Contrast

Compare usually requires direct relationship on shared dimensions and may include similarities and differences. Contrast foregrounds differences. The common error is to write two isolated descriptions. Strong responses make the relationship explicit: “Both methods…, but Method A…, whereas Method B…”. Always follow the convention used by the relevant subject or examination board.

Identify vs Analyse

Identify names the feature. Analyse explains how the feature functions, relates to other parts and contributes to the whole. “The writer uses repetition” identifies. “The repetition reinforces the speaker’s fixation and narrows the reader’s attention to one unresolved fear” begins analysis.

Analyse vs Evaluate

Analyse asks how something is structured or how its parts relate. Evaluate asks how good, effective, valid, important or suitable it is against criteria. An analytical answer can be excellent without making a judgement. An evaluative answer must ultimately decide what the evidence means for quality or value.

Assess vs Evaluate

Both involve judgement. Assess often targets a stated dimension—impact, risk, reliability, extent or feasibility. Evaluate often asks for a broader judgement against several criteria. This is not a universal distinction, so local subject guidance still matters. The practical rule is to identify the exact dimension named by the question and make the judgement visible.

Explain vs Justify

Explain gives the mechanism or reason something happens. Justify defends a choice, method or conclusion. “The value rises because demand increases” explains. “Method B should be chosen because it measures the target directly and can be repeated reliably” justifies. One is mechanism-centred; the other is defence-centred.

Challenge vs Rebut vs Refute

Challenge raises doubt about a claim. Rebut answers an opposing claim with reasons or evidence. Refute is strongest: it shows a claim to be false or untenable. Students often overuse refute. If the evidence merely weakens confidence, challenge is safer. If it answers the opposing case without decisively proving falsity, rebut is often more accurate.

Summarise vs Paraphrase vs Synthesize

Summarise compresses essential content. Paraphrase restates the same meaning in different wording while preserving scope and certainty. Synthesize combines multiple ideas or sources into a new coherent understanding. A student who paraphrases three sources separately has not necessarily synthesized them. Synthesis requires relationships across the sources.

Verify vs Validate

Verify checks correctness, authenticity or accuracy: verify a quotation, calculation or identity. Validate asks whether a method, measure or model is sound for its intended purpose. A sensor reading can be verified against a reference value; the measurement method can be validated as an appropriate way to measure the intended quantity.

Propose vs Recommend

Propose puts forward an idea for consideration. Recommend normally follows evaluation and selects the option that should be adopted. A proposal can be one candidate among several. A recommendation should explain why one candidate is preferable under the stated criteria and constraints.

The fastest revision method is to cover the explanations above and say the difference aloud in one sentence. Then apply each pair to a new topic. If the distinction survives a new context, it is becoming usable rather than merely familiar.

When two command words look similar, ask what changes in the answer procedure. That difference is the part worth learning.

One final examination habit

Before writing the first sentence, silently complete this line: “The question wants me to ______.” Replace the blank with an operation, not the original verb: “show why,” “compare directly,” “judge against criteria,” “defend a choice,” “infer from clues,” or “combine sources into a new conclusion.” That ten-second translation separates recognition from execution. It also gives the student a simple check at the end: did the answer actually perform that operation all the way through, or did it drift back into description because the topic felt familiar? In difficult examinations, that small habit can protect a large amount of knowledge from being routed into the wrong answer form.
