## About "cotton" in BIP39

- "cotton" has 6 letters, but the first three, **"cot"**, already identify it, because **"co"** also begins 40 other words, among them [coach](/bip39-word/coach/), [coast](/bip39-word/coast/), [coconut](/bip39-word/coconut/) and [code](/bip39-word/code/). Three letters are enough for only 604 of the 2048 words.
- **"cott"** is unique only within the English list: it also begins cottura in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
