Q: Is this SAT vocab list free?

Yes, and it needs no account. The quiz on the page runs without signing up.

Q: What is the best way to memorize SAT vocabulary?

Quiz first to find your gaps, read the example sentence before the definition, learn near-synonyms in groups, use word roots when a word will not stick, and space your second pass by a day.

This is the Pursu SAT vocabulary list: 542 words for the Digital SAT Reading & Writing section, each with a definition, part of speech, example sentence and near-synonyms. 188 of them are marked tested — those appeared as answer choices in real Words in Context questions in our own question bank, which is the evidence section further down.

Why a 1,000-word list is the wrong tool for the Digital SAT

Search for an SAT vocab list and the first results are lists of 1,000, 384 or 306 words to memorize. Those lists are a hangover from the pre-2016 SAT, which had sentence-completion questions built on obscure vocabulary. That test no longer exists.

The Digital SAT tests vocabulary through Words in Context questions, and what they actually ask for is narrower and harder than recall:

Near-synonym discrimination — four options are all plausible; only one fits the logic of the sentence. Knowing a definition does not settle it.
Secondary meanings — common words used in specialist senses, where the everyday meaning is the trap.
Tone and register — matching the connotation and formality of the passage, not just the denotation.
Contextual signals — using "but", "however", "in other words" and punctuation to infer a meaning you may never have seen.

Every one of those is a reasoning skill you practise, not a fact you memorize. That is why this list gives each word three questions in real passage context rather than a longer column of definitions. Three hundred words you can use beat a thousand you once read.

The words that actually appear on Words in Context questions

Most SAT vocabulary lists are assembled from other SAT vocabulary lists. We did something different: we went through 302 Words in Context questions in Pursu's own Digital SAT question bank and counted every word that appeared as an answer choice — 1,195 choices, 1,043 of them distinct.

The result is not what a vocabulary list looks like. The most-tested words are ordinary academic words used precisely — verify, validate, diminish, amplify, undermine, intermittent, conjecture, quantitative — not the rare words that fill traditional lists. That is the whole design of the question type: four options are all real words you probably know, and only one is exactly right for the sentence.

We checked our own list against this and it did not hold up. Of the 120 words that appeared in more than one question, only six were on our original 354-word list. Of 219 distinct correct answers, only three. The list was built on the vocabulary the old SAT tested, and the Digital SAT does not test that way. So the words below are being folded into the list, and this table stays on the page as the evidence.

Words appearing in more than one question

Ordered by how often each appeared across the 302 questions. "Correct" marks a word that was the right answer at least once — the others are the near-miss options you have to rule out, which is the harder half of the skill.

How to study this SAT vocab list

Reading an alphabetical list start to finish is the least effective way to use it. A better order:

Quiz first, read second. Start with the quiz below and let it find the words you do not know. Studying words you already know feels productive and is not.
Read the example sentence before the definition. That is the order the test uses — you meet the word in context and infer it. Training the other way round builds the wrong reflex.
Learn the near-synonyms together. Each entry lists synonyms and antonyms deliberately. The SAT rarely asks "what does X mean"; it asks you to choose between X and three words that nearly mean the same thing.
Use the etymology when a word will not stick. Most entries break down into roots and affixes, which is usually faster than brute repetition — and it transfers to words that are not on any list.
Come back after a day, not an hour. Spacing the second pass is the single highest-return change to how most students revise.

There is no need to finish all 354. Work the ones you miss, and the ones near them.

SAT Vocabulary FAQ

How many vocabulary words do I need for the SAT?

The Digital SAT no longer tests obscure words in isolation — it tests "Words in Context." But a strong core of 354–500 high-frequency academic words, like the list above, covers the vast majority of vocabulary you'll meet in real passages.

What is the best way to memorize SAT vocabulary?

Active recall beats re-reading. Use spaced-repetition flashcards, learn word roots so you can decode unfamiliar words, and practice each word inside a real sentence rather than memorizing a bare definition. Pursu's free tools do all three.

Does the Digital SAT still test vocabulary?

Yes — through "Words in Context" questions, where you pick the word that best fits a passage's meaning and tone. Knowing precise definitions and connotations of academic words like these is exactly what those questions reward.

How many words are on this SAT vocabulary list?

354 words, each with a definition, part of speech, example sentence, synonyms, antonyms and pronunciation — plus three practice questions per word, 1,062 in total.

Is 354 words enough for the SAT?

For the Digital SAT, yes — and the count matters less than people assume. Words in Context questions test whether you can choose precisely between near-synonyms in a passage, not whether you can recall definitions of rare words. Depth of practice on a focused list beats coverage of a long one.

Do I need to memorize 1,000 SAT words?

No. Thousand-word lists date from the pre-2016 SAT and its sentence-completion questions, which no longer appear on the test.

Is this SAT vocab list free? Do I need an account?

It is free and needs no account. The quiz on this page runs without signing up.

What is the best way to memorize SAT vocabulary?

Quiz first so you find the gaps, read the example sentence before the definition, learn near-synonyms in groups, use word roots when a word will not stick, and space your second pass by a day rather than an hour.
