“We should move the reading session” offers a proposal. “We should move it because the present time overlaps with another activity” adds a reason. A complete argument still needs to show whether the overlap is real, who it affects and why the proposed change is a suitable response.
An argument is not necessarily a quarrel. It is an attempt to make a position answerable to reasons and support. English gives writers ways to state claims, connect evidence, acknowledge competing considerations and limit conclusions without losing clarity.
This guide follows Questions and builds on Inference and Evidence. All examples concern imagined classroom arrangements; no invented count or incident is offered as real research evidence.

An argument answers a question that could reasonably receive more than one response. “Should the reading session move to another time?” establishes an issue. A history of reading sessions may provide background, but it does not automatically answer that issue.
Keep the question stable. A draft may begin by discussing timing and end by arguing that reading is valuable. The final position may be sensible, yet it has changed the task. Readers still need an answer about timing.
Write the issue in one plain sentence before drafting. Then check whether each major section contributes to answering it. If a different question becomes more useful, revise the opening honestly rather than quietly switching the subject midway.
“The session should begin at four” is a claim about an arrangement. “The current timetable lists three overlapping activities” is a factual claim. “The arrangement is fair” is an evaluation that needs a relevant standard of fairness.
Different claims require different support. A timetable can establish listed times; it cannot alone establish how every participant feels. A preference can explain what someone wants without proving that the arrangement serves everyone.
Make the claim specific enough to inspect. “Everything should change” hides the proposed action and its scope. “Move this session by thirty minutes, subject to room availability” gives readers a position they can evaluate against actual conditions.
CHAPTER 3 OF 20 · Identify the issue and case
3. Reasons explain why the claim deserves consideration
A reason connects the proposed position with something that matters. “The present session overlaps with the choir rehearsal” may be relevant if the argument aims to let affected students participate in both activities.
The reason should answer “Why this claim?” rather than merely restate it. “The new time is better because it is an improvement” does not provide a distinct basis. It repeats an evaluation in different words.
One good reason can be more useful than several unrelated advantages. If the issue is access, focus on access. Attractive details about refreshments or room decoration may distract unless the text explains why they matter to the decision being discussed.
CHAPTER 4 OF 20 · Identify the issue and case
4. Evidence supports a statement about the world
Evidence may include a verified timetable, recorded attendance, an attributed statement or other relevant information. Its usefulness depends on the claim it is asked to support.
In an imagined example, a timetable listing both activities from three to four would support the existence of a scheduled overlap. It would not establish that every choir member wants to attend the reading session, or that a later time is feasible.
When writing about an actual situation, identify the real source and its scope. When using an invented teaching case, keep it labelled as invented. Evidence has a responsibility that an illustration does not: it must actually provide a basis for the factual claim.
The bridge connects evidence to the position. “The two sessions overlap” becomes a reason for a change when the writer explains that affected students cannot attend both at the same time and that enabling participation is a relevant aim.
Without that bridge, readers may see the information but not why the proposed conclusion follows. With a weak bridge, the argument can still fail. An overlap alone does not establish which session should move.
Ask what assumption makes the connection work. Does the argument assume both activities are equally accessible at the new time? Does it assume the same room remains available? Make consequential assumptions visible and check them rather than leaving them hidden inside an apparently obvious conclusion.
CHAPTER 6 OF 20 · Inspect support and scope
6. Relevance is not the same as impressive detail
A source can be authoritative yet irrelevant to the particular issue. A general statement about the value of reading does not establish whether Thursday at four is an available slot.
Relevance depends on the claim. If discussing why the activity deserves support, the general statement may matter. If choosing a room, a booking record may be more directly useful.
Before inserting a fact or quotation, finish this sentence: “This helps support the claim because…” If the explanation changes the subject, reconsider the evidence. A crowded paragraph of impressive facts can leave the central position less supported than a short paragraph containing the right information.
CHAPTER 7 OF 20 · Inspect support and scope
7. Source quality and coverage both matter
A reliable source can have limited coverage. A room booking list may accurately report reservations while saying nothing about whether the room’s size suits the group. A participant’s account may accurately describe one person’s difficulty without representing everyone.
Inspect how the information was obtained, what it covers and when it applies. A past timetable may not describe the current arrangement. A copied quotation may omit a qualification important to its meaning.
Do not confuse source reputation with unlimited authority. Explain what the source can support in this argument. The reader should be able to trace the evidence and see the boundary between its information and the writer’s additional conclusion.
CHAPTER 8 OF 20 · Inspect support and scope
8. Quantity protects the size of the conclusion
“Three students reported a clash” supports a statement about those three reports. It does not establish that the entire class has a clash. “Most of the respondents” does not necessarily mean most of all eligible participants.
Name the relevant group and denominator when a proportion matters. In an invented case, six of eight respondents and six of forty eligible participants describe different relationships even though both include the number six.
Avoid expanding “some” into “all” while paraphrasing. A modest accurate claim gives the argument a firmer base. If the decision requires wider information, identify that need instead of enlarging a small observation through emphatic wording.
CHAPTER 9 OF 20 · Handle values and objections
9. Distinguish a factual premise from a value
“The activities overlap” concerns an arrangement that can be checked. “Students should have a reasonable chance to attend both” states a value or priority. An argument about a decision may need both.
Values are not made irrelevant by being different from factual observations. They help explain why the facts matter. But the writer should identify them rather than present them as if a timetable alone dictated the decision.
Different readers may share the facts and weigh priorities differently. One may prioritise continuity of the existing schedule; another may prioritise wider participation. A productive argument identifies the trade-off rather than accusing every disagreement of ignoring the evidence.
CHAPTER 10 OF 20 · Handle values and objections
10. Conditions make a proposal usable
“Move the session if the room is available and the new time does not create another clash” states conditions. These are part of the proposal, not decorative caution.
A condition can distinguish a supported recommendation from an overextended promise. The writer may have a good reason to investigate a change without enough information to demand immediate implementation.
Do not bury essential conditions after an emphatic unconditional opening. If the claim depends on availability, preserve that dependency in the claim itself or immediately alongside it. Clear qualification helps readers evaluate the actual proposal instead of an exaggerated version.
CHAPTER 11 OF 20 · Handle values and objections
11. Counterarguments identify serious competing considerations
A counterargument presents a relevant reason against the position or in favour of another response. “A later start would clash with the bus departure” is a serious consideration in a timetable discussion.
Represent the objection fairly. “Some people dislike improvement” is not a useful account of a practical clash. Weakening an opponent’s position makes it easier to dismiss but gives readers less help with the actual decision.
Look for the strongest reasonable objection, not the easiest one. The existing specialist guide on Opponent Modeling explores this practice more deeply. Here the beginner’s test is simple: would someone holding the other position recognise your description of it?
CHAPTER 12 OF 20 · Handle values and objections
12. A response can concede and still advance
An objection need not be answered by denial. “The later bus clash is a real limitation, so the proposed time is unsuitable for those students” concedes a relevant fact. The argument can then consider a different time or a narrower change.
Concession is not automatic surrender of every point. It means acknowledging what the evidence requires while preserving what remains supported. A proposal can improve by becoming more precise.
Explain what the objection changes. Does it defeat the whole claim, limit its scope or require another condition? Readers need that distinction. A paragraph beginning “However” should do more than signal that the writer refuses to move.
CHAPTER 13 OF 20 · Strengthen the reasoning route
13. Alternatives prevent false choices
“Move the session or abandon reading” presents a dramatic pair of options. The actual situation might allow a different day, two smaller sessions or a different room. An argument should not exclude relevant possibilities without a reason.
You need not evaluate every imaginable option. Select alternatives that are feasible enough to matter and explain the basis of comparison. Access, space and continuity may be useful criteria in the imagined case.
An alternative can reveal a hidden assumption. If a second session is possible, the argument may no longer be about moving the only session. Clarifying the real choice improves the reasoning before any persuasive language is added.
CHAPTER 14 OF 20 · Strengthen the reasoning route
14. Do not replace reasoning with personal labels
“The organiser is lazy, so the timetable is wrong” attacks a person without evaluating the arrangement. Even an accurate character judgement would not automatically establish whether the proposed time works.
Evaluate the relevant action, evidence or reasoning. “The timetable does not account for the listed rehearsal” identifies a problem that can be checked and repaired. It does not turn the problem into a permanent identity.
This distinction also helps disagreement remain useful. A person can make a mistaken proposal and later revise it. An argument should make that revision possible by identifying what needs to change, rather than making acceptance depend on humiliation.
CHAPTER 15 OF 20 · Strengthen the reasoning route
15. Avoid circular support and causal shortcuts
“The proposal is sensible because it is reasonable” repeats an evaluation. “Attendance rose after the change, so the change must be the only cause” turns sequence into an unsupported exclusive explanation.
Repair the first by naming a distinct basis, such as a verified reduction in clashes. Repair the second by inspecting other changed conditions and limiting the causal conclusion to what the evidence supports.
Reasoning errors are not solved by memorising labels alone. The useful skill is identifying the missing bridge or unsupported enlargement. Ask what additional information would make the conclusion defensible, and whether that information is actually available.
CHAPTER 16 OF 20 · Strengthen the reasoning route
16. Organise the case around the reader’s questions
Readers may need the issue, position and necessary background before inspecting reasons. They may then need evidence, explanation, a serious objection and a proportionate conclusion. This is a helpful route, not a universal paragraph formula.
Each section should advance the case. If two paragraphs give the same reason without new support, merge or develop them. If a counterargument appears before readers know the proposal, provide orientation first.
Do not save all qualification for the final sentence. Relevant limits belong where they affect the reasoning. Organisation should make the case inspectable rather than stage-manage readers into a conclusion before they encounter the information needed to evaluate it.
CHAPTER 17 OF 20 · Compare, revise and practise
17. Compare contributions to one argument
| Contribution | Invented timetable example | What to inspect |
|---|---|---|
| Claim | Investigate moving the reading session. | Is the action and scope clear? |
| Reason | Its time overlaps with choir rehearsal. | Why does that matter to the aim? |
| Evidence | The two listed sessions share the same hour. | Is the timetable current and verified? |
| Bridge | Affected participants cannot attend both simultaneously. | Does the relevant group face this constraint? |
| Qualification | Any new time must preserve room access and avoid another clash. | Are feasibility conditions checked? |
The table is a teaching model, not a report about an actual timetable. Its value lies in separating jobs that a fluent paragraph can otherwise blur together.
CHAPTER 18 OF 20 · Compare, revise and practise
18. Revise from certainty to support
Start with an overstated draft: “Everyone wants the session moved, and changing it will solve all attendance problems.” Underline “everyone”, “will” and “all”. What information supports those strengths?
A more proportionate version might say, “The reported clash gives us a reason to investigate another time. Before changing the schedule, we need to check room availability and whether affected participants can attend the alternative.”
This revision does not pretend that uncertainty makes action impossible. It identifies an appropriate next step. For deeper treatment of revisable conclusions, see Defeasible Reasoning. A good argument can recommend checking before committing.
Task 1. Does “The session should move because moving it is better” provide a distinct reason?
Answer. No. It repeats an evaluation. Name the problem the change addresses and explain how the proposed arrangement responds to it.
Task 2. Three respondents report a clash. Can the argument state that every participant has one? Answer. No. Preserve the observed group and identify whether wider information is needed.
Task 3. A proposed time clashes with a bus departure. Must the writer ignore this to remain persuasive? Answer. No. Acknowledge the limit and revise or test alternatives. Evidential strength matters more than preserving the original wording.
Task 4. Supply a bridge between “The labels are unreadable from the back” and “Use larger labels”. Possible answer. “Readers at the back need to identify the displays, so a readable size would address that visibility problem.” In a real case, check that size is the actual cause and that the revision is readable.
CHAPTER 20 OF 20 · Compare, revise and practise
20. Reconnect argument with persuasion
Argument makes a position answerable to reasons. Persuasion concerns influencing what readers think or do. The two can cooperate, but successful influence does not automatically establish a sound case.
When reading, ask what is claimed, what supports it and what the bridge assumes. When writing, make that reasoning visible and remain willing to revise the conclusion when relevant information changes.
The next guide, Persuasion and Responsibility, examines how language can attract attention and motivate action without concealing evidence, limits or choices. Return to the whole English map for the larger series.
