SAT® · Reading and Writing: Craft and Structure
Purpose Verbs and What Separates Them
Purpose verbs name the exact move a writer makes toward a claim. Qualify, concede, refute, criticize, and challenge are not interchangeable, and picking the wrong one turns a correct answer into a wrong one.
These questions ask what a sentence or author does to a claim, not just what it says. Illustrate means giving an example that supports a claim. Qualify means keeping the claim but attaching a condition that changes its scope or size, like saying a gain is bigger under certain circumstances. Concede means admitting a specific point has merit, often to set up a bigger objection right after it. Refute means showing a claim is false, with evidence or reasoning that closes the case. Criticize and challenge are weaker: they name a flaw or raise doubt without proving the claim wrong. Mixing these up is the whole trap. An author who says 'the model assumes a coastline that no longer exists' has criticized it, not refuted it, unless the text actually shows the model failing.
Conceding is easy to confuse with agreeing. Agreeing means accepting a claim fully. Conceding means accepting one piece of it, usually right before pivoting to disagreement. An author who concedes that a study was well designed, then argues its conclusion is wrong anyway, has not agreed with the conclusion at all.
This topic sits inside the larger skill of reading structure: tracking how a text moves from claim to evidence to response. The same care applies when evidence flips function, when numbers offered to support a claim end up undercutting it instead. Naming that shift correctly uses the same precise verbs.

Watch it explained
- How it worksHow do illustrate, qualify, refute, concede and challenge each name a different move in an argument?
- How it worksHow does conceding a point differ from agreeing with it when an author does it mid-argument?
- Worked exampleCompare two answers on one sentence: the first says it introduces a claim, the second says it summarizes one.
- Common mistakeWhy isn't 'criticize' the same as 'refute' when naming what an author does to a rival view?
- Going furtherWhat happens to a purpose verb like 'illustrate' when the example given actually undercuts the claim?
