## About "domain" in BIP39

- "domain" has 6 letters, but the first three, **"dom"**, already identify it, because **"do"** also begins 12 other words, among them [doctor](/bip39-word/doctor/), [document](/bip39-word/document/), [dog](/bip39-word/dog/) and [doll](/bip39-word/doll/). Three letters are enough for only 604 of the 2048 words.
- **"doma"** is unique only within the English list: it also begins domaine in the [French list](/french/), domato in the [Italian list](/italian/), domador in the [Portuguese list](/portuguese/) and doma in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
