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.
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.
A few dozen prefixes, roots, and suffixes — the building blocks that attach to almost everything.
Read an unfamiliar word apart into its parts, and its meaning is already there waiting for you.
A word is an assembly
Every word here is colour-coded by part. Tap one to take it to pieces.
The toolkit you start with
The pack opens with the prefixes — the directions and positions that snap onto any root.
One root, a whole family
Each cluster is a single Latin root and the English words descended from it. Learn it once.
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.
From plain to formidable
The pack runs five tiers, T1 to T5 — and the words grow up as you do.
- transportto carry from one place to another
- conspicuousclearly visible; attracting notice, often unwelcomely
- perfidiousdeliberately deceitful and untrustworthy; treacherous
- miscreanta person whose behaviour is criminal or morally wrong

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.
- Audio
- Clean Piper text-to-speech on every word and example sentence. CC BY / MIT / Apache-licensed voices.
- Lessons
- Reference lessons fire at the point in the sequence where they unlock what you're about to read.
