## About "lesson" in BIP39

- "lesson" has 6 letters, but the first three, **"les"**, already identify it, because **"le"** also begins 17 other words, among them [leader](/bip39-word/leader/), [leaf](/bip39-word/leaf/), [learn](/bip39-word/learn/) and [leave](/bip39-word/leave/). Three letters are enough for only 604 of the 2048 words.
- **"less"** is unique only within the English list: it also begins lessive in the [French list](/french/) and lessato in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
