Nobody with a large vocabulary built it word by word. They learned to read the parts. Meet irreparable and you can take it to pieces on sight — ir·re·par·able, "not able to be made ready again" — and read its meaning straight off the surface.

how vocabulary grows

The sum of its parts

Learn the parts, and the words assemble themselves.

Learn a single root — par: to make ready, to make equal — and a dozen words open at once. Prepare, repair, separate, compare, parity, peer, disparage, parade — and even emperor and rampart derive from this root. The next par- word you meet surrenders its meaning without a dictionary.

This is the vocabulary of serious English: the language of argument, law, history, and the sciences. The gap between nominal and token, renown and fame, and between thinking and cogitating. Precise words make precise thoughts — and roots are the parts precise words are built from.

The parts

A few dozen prefixes, roots, and suffixes — the building blocks that attach to almost everything.

The whole

Read an unfamiliar word apart into its parts, and its meaning is already there waiting for you.

Take it apart

One root, a whole family

Each cluster is a single Latin root and the English words descended from it. Learn it once.

par to make ready · to make equal from Latin parāre & pār
prepare repair separate compare parity peer disparage parade impair apparatus disparate emperor rampart

Thirteen words, one root. Once you can see the par in each, you never memorise them separately again — and the next one you meet falls open the same way.

Watch the register climb

From plain to formidable

The pack runs five tiers, T1 to T5 — and the words grow up as you do.

  1. transportto carry from one place to another
  2. conspicuousclearly visible; attracting notice, often unwelcomely
  3. perfidiousdeliberately deceitful and untrustworthy; treacherous
  4. miscreanta person whose behaviour is criminal or morally wrong
  5. stringentstrict, precise, and exacting
How it sticks

Flashcards as an integrated system

Paired cards
500 cards, 1,000 words — each card pairs a headword with a relative from the same family, so the word and its kin arrive together.
Fibonacci SRS
Rate each card 0–5. The better you know a word, the longer before it returns — spaced repetition on Fibonacci intervals.
Boss fights
Each root family is gated by a duel you can't win without confronting and overcoming its hardest members.
Graduation
Beat a family and its cards leave your daily deck for good. The deck gets smaller as you learn.
Etymology
Every card shows the root, its Latin source, and exactly how the parts assemble — plus synonyms and antonyms to place each word precisely.
