College Board includes Words in Context within Craft and Structure. Learn a definition, but check how the writer uses the word in the passage before you choose an answer.

Key term

Words in Context
A Digital SAT Reading and Writing question type that College Board includes within Craft and Structure. You choose the word or meaning that fits how the writer uses it in the passage, so a memorized definition is only the starting point.

From our practice data: on The Test Advantage, students answered Words in Context questions correctly 68% of the time, below their Reading and Writing average of 71% (sample of 193 Words in Context answers from 74 students, late June to late September 2026).

This page is the short list to start with. For a full reference, use 1000 SAT words and definitions. For an alphabetical list of Digital SAT words from 2023 to 2025, see the SAT vocabulary list A to Z. Watch the vocab videos to hear Mr. O use SAT words in context.

Study this SAT words list a small set at a time

Choose ten unfamiliar words. Cover the definitions and write a sentence for each. Compare your sentence with the meaning, then mark the words you need to revisit. The examples below illustrate usage; they are not official SAT questions.

Words can have several senses. A positive or negative association can help you interpret a passage, but it does not settle the answer. Check the precise meaning and grammar of the sentence.

Words 1 to 30

1. Ambiguous
adjective
Having more than one possible meaning; unclear.
"The senator's statement was ambiguous. Supporters claimed it endorsed the bill while opponents said it did not."
SAT Pattern: Passages describe communication or findings where the intended meaning is unclear. Look for context clues like "could mean either" or "interpreted differently."
Synonyms: unclear, vague, equivocal, indefinite
Memory tip: Ambiguous = both ways. Like a road sign that could mean turn left or go straight.
2. Corroborate
verb
To confirm or support with evidence.
"The new geological data corroborated the researcher's earlier findings about the ancient coastline."
SAT Pattern: Science and research passages use this when new evidence supports an existing claim. Opposite of contradict. If the passage says two sources agree, the answer is often corroborates.
Synonyms: confirm, support, substantiate, verify, validate
Memory tip: Corroborate = confirm. Think of a witness who confirms what another witness said.
3. Skeptical
adjective
Not easily convinced; having doubts about a claim.
"Many scientists were skeptical of the initial results and demanded the experiment be repeated."
SAT Pattern: Appears in passages describing academic debates. When someone remains skeptical despite evidence, the passage is setting up a complication.
Synonyms: doubtful, questioning, unconvinced, dubious
Sign: Negative toward the claim. The person does not believe something yet.
4. Refute
verb
To prove that something is false or incorrect.
"The study effectively refuted the long-held belief that regular multitasking improves cognitive function."
SAT Pattern: Common in science passages where a new study disproves something. Refute means prove wrong, not just argue against.
Synonyms: disprove, contradict, counter, debunk
5. Pragmatic
adjective
Practical and realistic rather than theoretical or idealistic.
"Her pragmatic approach meant she chose the method most likely to work quickly, not the theoretically perfect one."
SAT Pattern: Often appears in contrast with idealistic or theoretical. If a person solves a real problem without obsessing over abstract principles, they are pragmatic.
Synonyms: practical, realistic, sensible

When a word you studied still costs you the question

From our practice data: On The Test Advantage, accuracy falls as a question's difficulty label rises: 80% on Easy, 72% on Intermediate and 62% on Hard questions (random sample of 1,769 practice answers, 422 Easy, 867 Intermediate and 480 Hard, from 100, 139 and 101 students, Jun–Sep 2026). These figures cover every question type, not vocabulary alone.

So a clean run on easy questions is weak proof that a word list has stuck. Check yourself on harder sentences too. In the original example below, the word comes from this list, and the sentence decides which sense of it you need.

Worked example: the word you know, in the sense you skipped

Although the pilot study's early results were encouraging, the research team chose to ______ its enthusiasm in the published report, noting that data had been collected at only twelve sites.

  • A) temper
  • B) validate
  • C) disseminate
  • D) exacerbate
Show the answer and the trap

A. "Although" sets up a contrast with "encouraging," and "only twelve sites" is a limit. The team is holding its enthusiasm back, which is this list's meaning for temper (word 98): to moderate or soften. B and C are the traps. Research teams do validate findings and disseminate results, so both words fit the topic, but "validate its enthusiasm" and "disseminate its enthusiasm" ignore the contrast. D means to make a problem worse, and enthusiasm is not the problem here. If you know "temper" only as a noun for anger, A looks wrong at first glance. Read the sentence for the sense it needs.

How to practice this on The Test Advantage

Open the Digital SAT question bank and pick an English bank by test month, year and form. One bank is free to access. On each vocabulary question, cover the choices and write your own word for the blank before you look. After you submit, check the answers and explanations. If your word matched the key's meaning but you still picked another choice, the choices misled you, not the word. Add the sense you missed to your review set.

Check your reasoning in a fresh question

After studying a set, try a Words in Context question without the list beside you. Explain the meaning the blank requires before choosing an answer. If you miss it, record whether you lacked the word's meaning or overlooked a clue.

Testing on November 7? Our November 2026 SAT vocab predictions show which Words in Context questions have already repeated in our question banks, so you know what to practice first.
