Recap
- A thesis statement presents a claim that requires proof or defence.
- It may preview the line of reasoning, meaning it signals how the argument will develop.
- A preview is not required to list points, aspects to be analysed or specific evidence.
- In reading, identify the thesis and what it indicates about structure. In writing, write a thesis that may preview the structure.
Key relationships
| Form | Example pattern | Preview? |
|---|---|---|
| Claim only | “X should happen.” | No, but acceptable |
| Claim + governing reason | “X should happen because Y.” | Partly |
| Claim + reasons in order | “X should happen because A, B and C.” | Yes |
| Concession + claim | “Although P, X should happen because Q.” | Yes: signals acknowledgment then reasoning |
| Progression (analysis) | “By moving from A to B, the writer…” | Yes: signals stages |
| Announcement | “This essay will discuss A, B and C.” | No: a task, not a claim |
| Bare list | “A, B and C are all relevant.” | No: no claim |
| Reading step | Question |
|---|---|
| 1 | Which sentence takes a position? |
| 2 | Which words signal reasons, order or progression? |
| 3 | Do the topic sentences follow the signals? |
| 4 | What does that tell you about the writer’s purpose? |
Assumptions and conventions
- A thesis can be one or two sentences.
- It usually sits at the end of the introduction but may appear elsewhere.
- Match the level of detail to the length of the argument.
- If you change the order of the body, change the preview.
Mistakes to avoid
- Writing “In this essay I will…” instead of a claim.
- Listing labels (“ethos, pathos and logos”) without saying what they do.
- Listing three reasons that do not support the claim.
- Promising reasons you do not develop.
- Over-long theses that bury the claim.
- Treating a preview as compulsory and forcing it where one governing reason would do.
- Naming the preview without describing its structural signal when analysing a text.
Worked mini-example
Claim: a school should add a quiet room at lunchtime.
Announcement: “This essay will talk about quiet rooms, noise and lunch.”
Preview: “A school should add a quiet lunchtime room, because it would help students who find the canteen overwhelming, give clubs a place to meet and cut corridor arguments.”
The preview makes a claim, gives three reasons in order and can be argued with. The body then follows the same order: students, clubs, corridors.
On the exam
When you plan an essay, write the thesis last, after you have decided the order of your reasons, so that the preview is accurate. In reading questions, quote the clause that signals the structure.
Quick self-check
- Is “This essay will examine homework, sleep and stress” a preview? (No: an announcement with no claim.)
- What does “Although the plan costs money, it should be adopted because…” signal about structure? (A concession followed by reasons.)
- A thesis names reasons A, B and C but the body argues C, A, then D. What should the writer do? (Revise the thesis or the body so they agree.)
