The GRE and SAT word list

14 prep lists in. One ranked list out.

Every prep book prints its own word list, and they disagree. We cross-referenced 14 of them and ranked every word by how many agree it matters, so your first set is the one nearly every list includes.

Ranked by agreement, not the alphabet.
Rank 1 is on 13 of 14 lists. You meet the sure things first, in sets of 30.
A ladder with an end.
Must-Know, High-Frequency, Extended, Long Tail. Stop where your exam date says to.
SAT, built the same way.
1,100+ SAT words ranked across 4 SAT lists. A word on both exams is learned once.

Vocabulary mnemonics

A silly sentence beats a hundred re-reads.

Every hard word gets a hook: something that already sounds like it, dropped into a scene small enough to picture and pointed enough to give the meaning away. You do not memorize obdurate. You remember an old door that will not budge.

27,000+ hooks across the corpus.
Every word carries a handful, so there is always one that lands for you.
Authored, judged, reviewed.
A written house style, a scoring rubric, and a pass set by set before anything shipped.
Sound first, always.
No Latin, no leaning on another exam word — just a sound you already own.

Words it builds

Word roots

Learn one part, and a family comes with it.

Long words are built from short parts. Learn one piece of Latin and you have not learned one word — you have a way into every word built from it, and a fighting chance at the next one you meet. Pull a few words apart and the same handful of pieces keeps coming back.

obdurate is the same word whose hook was “the OLD DOOR” — a sound to hold it and a structure to explain it. Two ways into one word.

600+ word parts.
Prefixes, roots and suffixes, each with the words it actually builds.
5,200+ words broken into those parts.
Each one split into its prefix, root and suffix, with a gloss under every piece.
It keeps working after the list ends.
Meet a word you have never seen and the parts still tell you which way it points.

Word themes

Words travel in packs. Learn the pack.

garrulous, loquacious, verbose, prolix — one idea, four words, and the exam is going to ask you which of them swap cleanly for each other. So they arrive together, with the family that means the opposite sitting right beside them.

laconic was the first word on this page. It lives one card away from garrulous — and knowing that is the whole trick to a sentence-equivalence question.

Inside every word

A definition is the least of it.

The exam does not ask what a word means. It asks whether it fits this sentence, whether it flatters or stings, and which look-alike you have mixed it up with. So every entry carries all of that.

Every word has its pronunciation, origin, example sentences, synonyms, a note on how it feels and a set of hooks. Opposites, look-alikes, word parts and meaning families appear wherever a word has them.

That is three ways into a word. A daily plan, a story for every set and the games are further down.

The rest arrives on launch day. One email, then nothing.

Coming soon to the App Store. On Android, the beta is on Google Play now.

Vocab Mountain

One right thing to do today.

Pick a list and a schedule, and the app stops asking you what to study. Every day you learn one new group of 30 and review the groups behind it. Come back tomorrow and the day is already laid out.

Two schedules, one list.
Classic is cumulative — day 40 is 40 groups. Steady holds the daily load flat at about ten groups however long the list runs.
A real scheduler underneath.
FSRS spaced repetition decides when each individual word comes back, so the ones you keep missing come round sooner than the ones you don't.
100+ GRE sets, 35+ SAT sets.
Ranked by how many real prep lists each word appears on, so the first group you climb is the one that pays first.

The two schedules follow the Vocab Mountain method popularized by GregMat. SnapVocab is not affiliated with GregMat.

Chapter One

A Plan

Bolt Bakes a Cake

Bolt had never baked before. On Monday night his plan still looked . He had a picture of a cake and nothing else. Then he pulled down every book on the shelf. The pile grew . It held books about boats, books about birds and one about the moon. One book helped. Its steps were short and , so Bolt copied them out.

Grandpa was before his morning tea. Bolt waited until the kettle had boiled and then asked about eggs. Grandpa answered in five words. He spoke in a way until noon. Nina was the opposite at breakfast. She chattered in a stream about her socks and a duck-shaped cloud. Grandpa stayed about his birthday, so Bolt never learned what he wanted.

Set Stories

Thirty words, one short story.

Finish a set and a story is waiting that uses all 30 of its words, plainly enough that you can work most of them out. Tap anything you're unsure of. It is not a quiz — nothing is scored and nothing is withheld.

130+ stories, one per set.
Written to a picture-book register on purpose: short sentences around each hard word, so the sentence itself does the teaching.
Every word doing its job.
Not a word list in paragraph form. "A small kitchen robot spends a week learning to bake a birthday cake for Grandpa." — and all thirty of Set 1's words earn a place in it.
The last page tells you where you stood.
It splits what you read from context against what you looked up — the honest measure of which words are actually yours.

Vocabulary games

Games that train a skill, not your thumbs.

Not one quiz in a dozen costumes. Each board trains a different skill, and each has its own ladder of curated levels that get harder as you climb.

  • Woolgather

    Word Groups

    Five words share a meaning. Cut the one that only looks like it does.

  • The Sorting Office

    Nuance & Context

    File each word by the feeling it carries: praise, blame, or neither.

  • Compositor

    Word Groups

    Build the word the definition asks for out of a prefix, a root and a suffix.

  • Doppelganger

    Nuance & Context

    Tell apart the look-alikes and sound-alikes that swallow marks.

  • The Margin

    Nuance & Context

    Mark the span of a document that does no work — or say there is nothing to cut.

  • Locksmith

    Spell & Recall

    Spell the word from its meaning, with only the first letter to go on.

And the classics, done properly.

Make it yours

Bring your own words. Write your own hooks.

The curated lists are the starting point, not a fence. Your professor's reading list, the words you keep missing, the hook only you would think of: they all study the same way.

Import your own list Pro

Paste a list or upload a file, and it becomes a list like any other: sets, flashcards, spaced review and all.

Write the hook only you would think of

Every word comes with curated hooks, and the best one is sometimes your own. Write it once and it becomes the hook on your card.

Stuck on a word? Ask. Pro

Ask a question about any word, or have a few hooks suggested for a word of your own. It helps with your words; the curated lists never depend on it.

Staying with it

Built for day forty, not just day one.

Learning a few thousand words is a months-long habit. These are the small things that make tomorrow's session easier to start.

Duels with friends

Send a friend the exact board you just played. They answer when they have five minutes, and the scores meet in the middle.

A word on your home screen

The widget puts one word where you will see it twenty times a day, before you open anything.

Streaks and weekly leagues

A streak for showing up, and a league table you climb by studying. Finish the week near the top and you move up a league.

No ads. No trackers.

Nothing is sold to you mid-session, on the free plan or on Pro, and the app ships without an analytics or advertising SDK.

Works on the train.

With Pro you can download your lists and practice with no connection. It is a practice mode: your scheduled reviews pick up again once you are back online.

Free is a real plan, not a trial.

Start with the words that matter most and pay nothing. Pro opens the rest for $4.99 a month or $29.99 a year, with a 7-day free trial on the yearly plan.

Right now, Pro is free in the beta.

Questions, answered plainly.

Can I download SnapVocab today?

On Android, yes: SnapVocab is on Google Play as a closed beta that anyone with a Google account can join from snapvocabapp.com/android. It is not on the App Store yet; on iPhone, join the waitlist and we will send you one email on launch day.

Which exams does it cover?

GRE and SAT. The GRE list has 3,000+ words in 100+ sets, and the SAT list has 1,100+ words in 35+ sets. Words that appear on both are learned once and count for both.

How were the words chosen?

We took 14 published GRE prep lists and 4 SAT lists and ranked every word by how many of them include it. You study in sets of 30, starting with the words the most lists agree on, so the early sets are the ones most worth your time.

Where do the mnemonics come from?

They are written to a house style: an everyday sound-alike, inside a tiny scene that gives away the meaning. Every one was reviewed against a written rubric before it shipped, and weak ones were rewritten. They are not generated when you tap a button, so you never get a confusing or wrong one on the fly.

Can I get Pro free during the beta?

Yes. Pro is a paid subscription, but while SnapVocab is in beta every new account gets Pro free within 24 hours, with no card and nothing to cancel. If yours did not, email hello@snapvocabapp.com and we will add it. The free plan stays free either way.

Is there a free plan?

Yes. The free plan includes the first tier of each word list, six of the games, thirty word themes and daily duels, with no ads. Pro unlocks every list tier, every game and theme, your own word lists, and offline downloads. Pro is a paid subscription.

Can I add my own words and mnemonics?

Yes. With Pro you can paste or upload your own word list and study it like any built-in list. On any word you can also write your own mnemonic, and it becomes the hook on your card. Pro can suggest hooks for your own words and answer questions about a word.

How does it decide what I review?

Flashcards run on FSRS, a modern open spaced-repetition algorithm. You grade each card Again, Hard, Good or Easy, and the scheduler decides when that word should come back, so you spend your time on the words you are about to forget.

How much do I have to do each day?

You choose the pace. Vocab Mountain gives you one clear task each day: a new set of words plus a review of the sets behind it. The Classic schedule reviews everything you have learned so far; the Steady schedule caps the daily load at about ten sets, however long your list is.

Your exam has a date. Your words should too.

One set a day, a hook for every word, and a scheduler that remembers what you are about to forget.
