Argumentative writing is not about sounding certain. It is about making a claim that can survive questions.
The Secondary 2 Essential 100 Vocabulary contains many words that matter here: assert, assess, bias, consequence, evaluate, evident, feasible, justify, legitimate, significant and validate. This article turns them into argumentative tools.
Quick Read: An Argument Has Parts
- claim — what you want the reader to accept;
- reason — why the claim may be true;
- evidence — what supports the reason;
- warrant — why the evidence connects to the claim;
- counterargument — a serious alternative view;
- qualification — where the claim should be limited;
- conclusion — what follows after weighing the evidence.
Vocabulary for Claims
- argue;
- contend;
- maintain;
- assert;
- propose;
- suggest.
These verbs differ in force. Suggest is cautious. Assert is stronger. Match the verb to the confidence and evidence available.
Vocabulary for Evidence
- evidence indicates;
- data suggest;
- examples illustrate;
- the pattern is evident;
- the finding supports;
- the evidence is insufficient.
Do not write “this proves” unless the evidence genuinely supports such certainty.
Vocabulary for Reasoning
- therefore;
- because;
- consequently;
- this suggests;
- the implication is;
- this is significant because.
The reasoning sentence is where many arguments fail. Evidence does not explain itself. Tell the reader why it matters.
Counterargument Vocabulary
- however;
- critics may argue;
- an alternative view is;
- although;
- while this concern is legitimate;
- on the other hand.
A counterargument should be strong enough to deserve an answer. Inventing a weak opposing view only makes the essay look less rigorous.
Qualification Makes Arguments Stronger
“Social media is harmful” is broad. “Social media can be harmful when recommendation systems repeatedly amplify misleading or inflammatory content” is narrower and more defensible.
- may;
- can;
- often;
- in some contexts;
- predominantly;
- to some extent;
- provided that.
Use Evaluative Vocabulary with Criteria
Calling a policy effective, feasible, equitable, legitimate or beneficial implies a criterion. Explain what counts as effective or feasible in this context.
A Model Argument Paragraph
“Schools should allow limited student choice in project topics because autonomy can increase engagement. When students investigate questions they genuinely care about, they may sustain attention for longer and take greater responsibility for the quality of the work. However, complete freedom may be infeasible if topics require resources or expertise the school cannot provide. A stronger approach is therefore guided choice within clear academic and logistical boundaries.”
The paragraph makes a claim, explains a mechanism, acknowledges a limitation and refines the position.
Avoid Absolute Language
Words such as always, never, everyone, completely, undoubtedly are risky unless the claim truly supports them. Precise qualification often sounds more mature than exaggerated certainty.
Avoid Emotion Without Evidence
“This outrageous rule is obviously terrible” generates temperature but not reasoning. “The rule is difficult to justify because it imposes substantial cost while evidence of benefit remains limited” gives the reader something to evaluate.
Argument Vocabulary Bank
| Job | Useful vocabulary |
|---|---|
| claim | argue, assert, propose, contend |
| evidence | indicate, demonstrate, support, validate |
| evaluation | feasible, legitimate, significant, sufficient |
| counterargument | however, although, critics argue |
| qualification | may, often, under these conditions |
| conclusion | therefore, overall, consequently |
A Practice Routine
- Write one claim.
- Add one reason.
- Add evidence.
- Explain why the evidence matters.
- Write the strongest counterargument.
- Qualify your original claim if necessary.
- Conclude with the narrowest defensible position.
Argument Is Vocabulary Under Pressure
Use the Secondary 2 Essential 100 as a base, then practise matching words to evidence, certainty and scope. The strongest argument is not the loudest one. It is the one whose language accurately represents what the evidence can support.
Argument Laboratory: Build Claims That Survive Intelligent Objections
A useful argument is not one that sounds impossible to challenge. It is one that becomes clearer when challenged. Questions reveal missing assumptions, weak evidence and claims that are broader than the reasoning can support.
The Claim–Evidence–Warrant–Limit Model
- Claim: What conclusion are you asking the reader to accept?
- Evidence: What observation, example, data or source supports it?
- Warrant: Why does that evidence make the claim more plausible?
- Limit: Under what conditions should the claim be narrowed?
The warrant is especially important. “Most surveyed students prefer later starts” is evidence about preference. To argue that later starts improve learning, the writer must explain why preference is relevant—or provide evidence about sleep, attention or performance instead.
Worked Argument: Should Schools Reduce Printed Worksheets?
Claim: Schools should reduce unnecessary printing rather than eliminate printed materials entirely.
Reason: Digital distribution can reduce paper use for materials that do not require handwriting or physical annotation.
Counterargument: Some students read or annotate more effectively on paper, and device access may not be equally reliable.
Refined conclusion: A selective policy is more feasible than a blanket ban because it preserves print where its instructional benefit is significant while reducing routine waste elsewhere.
The refined position is stronger because the counterargument changes the claim instead of appearing as a paragraph that is politely ignored.
Counterarguments Should Touch the Strongest Part of Your Position
A weak counterargument says, “Some people may disagree.” A serious counterargument identifies a cost, assumption or competing value. If you argue for more student choice, the strongest objection may concern quality control, resource constraints or unequal access—not simply that some teachers prefer existing practice.
Rebuttal Has Several Forms
| Move | What it does | Useful language |
|---|---|---|
| reject | show the objection is unsupported | this assumes…, the evidence does not establish… |
| qualify | accept part and narrow the claim | this concern is legitimate when…, although… |
| outweigh | accept a cost but argue another factor matters more | while the cost is significant, the greater consideration is… |
| redesign | modify the proposal to address the objection | a more feasible approach would… |
Separate Values from Evidence
Two people can agree on the facts and disagree because they value different outcomes. One prioritises fairness; another efficiency. One values autonomy; another consistency. Strong argumentative vocabulary makes the value criterion visible instead of pretending the disagreement is purely factual.
Scope Is Part of the Claim
Words such as some, many, often, under certain conditions, predominantly and may are not filler. They define the population and circumstances to which the argument applies. “Group work improves learning” is far broader than “well-structured group work can improve learning when students have distinct roles and a task that genuinely requires collaboration.”
Argument Editing: The Hostile Reader Test
- Imagine a careful reader who disagrees with you.
- Underline every claim they could reasonably ask you to prove.
- Mark the evidence supporting each claim.
- Write the missing warrant where the connection is not obvious.
- Find the strongest objection.
- Decide whether to rebut, qualify, outweigh or redesign.
Intellectual Honesty Improves Persuasion
Admitting a limitation can increase credibility when the limitation is real. “This survey cannot establish long-term effects” tells the reader that the writer understands what the evidence can and cannot do. Pretending weak evidence is conclusive makes sophisticated readers trust the argument less.
Checkpoint: What Would Change Your Mind?
Write one piece of evidence that would weaken your conclusion. If no imaginable evidence could alter your position, you may be defending an identity or value commitment rather than evaluating an empirical claim. That distinction is useful to recognise.
