Alphabetical vocabulary lists are the wrong shape for this test. The digital SAT doesn't ask what a word means — it asks which sense of it fits a particular sentence, which is a question about connotation and function. So these words are grouped by the job they do. The first group is the one that costs students the most points, and almost every word in it is a word you already know.
On how this list was built: the groupings come from the patterns visible across College Board's released practice material and question bank, not from a proprietary frequency count. Treat the categories as the durable part and the individual words as representative rather than exhaustive.
Group 1 — Familiar words, second meanings
The highest-value group on this page, and the one nobody studies, because every word here looks like a word you already know.
This is the SAT's favourite trap in words-in-context questions. The passage uses compromise, you read it as "reach a middle ground," and the sentence quietly meant "weaken." The wrong answer that matches the everyday sense is always on offer.
| Word | The sense the SAT wants |
|---|---|
| compromise | to weaken or undermine |
| novel | new, original |
| qualify | to limit or restrict a claim |
| sound | valid, well-founded |
| yield | to produce |
| arrest | to halt |
| check | to restrain |
| coin | to invent (a term) |
| discriminate | to distinguish between |
| economy | efficiency, sparingness |
| exploit | to make use of (neutral) |
| flag | to weaken, lose energy |
| ground | basis, foundation |
| harbor | to hold (a belief, a doubt) |
| observe | to remark, to comment |
| reservation | a doubt or hesitation |
| sanction | to approve — or to penalise |
| sustain | to support, to uphold |
| temper | to moderate, to soften |
| treat | to deal with (a subject) |
| want | a lack |
| warrant | to justify |
| weather | to endure |
| bearing | relevance |
| capacity | a role or function |
| constitute | to make up, to comprise |
| convention | an accepted practice |
| couch | to express (in certain terms) |
| degree | extent |
| fashion | a manner; or to make |
| foil | a contrast; or to thwart |
| gravity | seriousness |
| indifferent | mediocre, unremarkable |
| pedestrian | ordinary, uninspired |
| provincial | narrow in outlook |
| relate | to recount, to tell |
| render | to cause to become |
| spare | plain, unadorned |
| static | unchanging |
| stem | to originate |
| store | value, importance |
| strain | a variety or type |
| succeed | to follow after |
| tender | to offer formally |
| utility | usefulness |
| vein | a style or manner |
| volume | quantity |
| appreciate | to increase in value; to grasp fully |
| affect | to adopt or feign (as a verb) |
| scores | large numbers |
Group 2 — What the author is doing
These earn their place twice. They show up as vocabulary answers, and they're the language of purpose and structure questions — where you have to name what a writer is doing in one verb. That habit is the fix for purpose questions, and this is its raw material.
| Putting a view forward | Agreeing or conceding | Pushing back |
|---|---|---|
| assert | concede | refute |
| contend | acknowledge | rebut |
| posit | grant | counter |
| postulate | affirm | dispute |
| maintain | endorse | contest |
| propose | corroborate | challenge |
| advance | echo | question |
| advocate | defer to | dismiss |
| champion | concur | reject |
| espouse | ratify | repudiate |
| hypothesize | denounce | |
| speculate | debunk | |
| surmise | undercut | |
| infer | call into question |
Group 3 — Change and effect
Cause-and-effect vocabulary, heavily used in science and social science passages. Direction matters more than intensity here: notice which words strengthen and which weaken, because reversed-relationship answers are a standard inference trap.
| Strengthens / increases | Weakens / decreases |
|---|---|
| augment | curtail |
| amplify | diminish |
| bolster | dwindle |
| buttress | erode |
| catalyze | attenuate |
| exacerbate (worsens) | mitigate |
| facilitate | hinder |
| foster | impede |
| galvanize | stifle |
| engender | quell |
| spur | forestall |
| proliferate | subvert |
| precipitate (brings about) | undermine |
| supplant (replaces) |
Group 4 — Hedges and degrees of certainty
Learn this group and inference questions get easier immediately. Passages hedge; overreaching answers don't. Spotting the mismatch between a hedged text and a categorical answer choice is one of the fastest eliminations on the test.
| Hedged / tentative | Strong / categorical | Frequency |
|---|---|---|
| ostensibly | categorically | invariably |
| purportedly | unequivocally | uniformly |
| seemingly | demonstrably | consistently |
| arguably | conclusively | sporadically |
| presumably | definitively | intermittently |
| conceivably | indisputably | episodically |
| plausibly | emphatically | perennially |
| tentatively | ||
| provisionally | ||
| nominally |
If the passage says suggests and an answer says proves, that answer is wrong — regardless of how well its content matches. Certainty mismatch is the most reliable elimination in Information and Ideas, and it needs no rereading at all.
Group 5 — Evidence and support
Command of Evidence questions live here, and so does a lot of the science vocabulary in passages about studies and findings.
| Word | Sense |
|---|---|
| corroborate | confirm with independent support |
| substantiate | establish with evidence |
| validate | confirm the soundness of |
| vindicate | show to have been right after doubt |
| attest | provide evidence of |
| evince | reveal, make evident |
| underscore | emphasise |
| reinforce | strengthen an existing case |
| bear out | confirm in practice |
| exemplify | serve as a typical case |
| empirical | based on observation or experiment |
| anecdotal | based on individual accounts, not data |
| preliminary | early, not yet conclusive |
| conclusive | settling the question |
| rigorous | carefully and strictly conducted |
| replicate | reproduce a result independently |
| confound | to muddle a result with an outside factor |
| spurious | false, not genuine |
Group 6 — Contrast, tension, and surprise
These mark the turn in a passage, which makes them structure vocabulary as much as word-meaning vocabulary. Find the turn and structure questions usually answer themselves.
| Word | Sense |
|---|---|
| notwithstanding | despite |
| albeit | although |
| conversely | from the opposite direction |
| paradoxically | in a self-contradictory way |
| counterintuitively | against what you'd expect |
| anomalous | deviating from the pattern |
| incongruous | out of keeping with the rest |
| disparate | fundamentally different |
| divergent | moving apart |
| belie | to contradict or misrepresent |
| obscure | to hide, to make unclear |
| complicate | to add difficulty to a claim |
| caveat | a warning or qualification |
| nuance | a subtle distinction |
| ostensible | apparent but perhaps not real |
| at odds with | in conflict with |
For the connective versions of these — however, nevertheless, consequently and the rest — see our transition words guide, which sorts them by logical relationship.
Group 7 — Tone and attitude
Used when a question asks how an author regards something. The trap is picking a tone that's too extreme: SAT authors are overwhelmingly measured, and answers like contemptuous or euphoric are usually there to be eliminated.
| Word | Sense |
|---|---|
| ambivalent | holding mixed feelings |
| circumspect | cautious, wary |
| skeptical | doubting |
| dismissive | treating as unworthy of attention |
| deferential | respectful, yielding |
| laudatory | praising |
| disparaging | belittling |
| measured | restrained, careful |
| emphatic | forceful |
| wry | dryly humorous |
| candid | frank |
| equivocal | deliberately ambiguous |
| dispassionate | neutral, unemotional |
| polemical | strongly argumentative |
| conciliatory | seeking to reconcile |
| indignant | angry at unfairness |
| resigned | accepting something unwelcome |
| sanguine | optimistic |
Group 8 — How much, how many
| A lot | Very little |
|---|---|
| ubiquitous | scant |
| pervasive | sparse |
| prevalent | negligible |
| myriad | marginal |
| manifold | dearth |
| prodigious | paucity |
| copious | finite |
| surfeit | discrete (separate, not "discreet") |
How to actually use this
Reading the list start to finish will do very little. Three things will:
- Predict before you look. Read the sentence, cover the four choices, and say your own word for the blank. Then find the closest match. Browsing the options first is how you get pulled toward whichever word sounds most impressive, which is precisely what the wrong answers are built to exploit.
- Start with Group 1. Fifty words, all of them already familiar, all of them capable of costing you a question because you're confident in the wrong sense. Best return on this page by a distance.
- Learn Groups 2 and 4 as tools, not vocabulary. Group 2 gives you the verbs for naming what an author is doing, which is the method for purpose questions. Group 4 gives you the certainty mismatch, which is the fastest elimination in inference. Both pay off on questions that aren't about vocabulary at all.
Then drill it properly: filter the official Question Bank to words-in-context questions and work through them logging every miss, rather than re-reading the list. The Question Bank is free and badly underused.
Frequently asked questions
Do you still need to memorise vocabulary for the SAT?
Not as flashcards. The test asks which sense of a word fits a sentence, so connotation and context matter more than definitions.
What kind of vocabulary is on the digital SAT?
Ordinary academic English, plus familiar words used in secondary senses — compromise, novel, qualify, sound. That last group causes the most damage.
How many words should I learn for the SAT?
A few hundred, grouped by function. Forty words describing what an author does will serve you on more questions than four hundred rare nouns.
What is the best way to study SAT vocabulary?
Predict before you look at the choices. Lists only help if paired with that habit.
