## About "vast" in BIP39

- "vast" has 4 letters, but the first three, **"vas"**, already identify it, because **"va"** also begins 11 other words, among them [vacant](/bip39-word/vacant/), [vacuum](/bip39-word/vacuum/), [vague](/bip39-word/vague/) and [valid](/bip39-word/valid/). Three letters are enough for only 604 of the 2048 words.
- **"vast"** is unique only within the English list: it also begins vaste in the [French list](/french/), so a four-letter backup should say which list it uses.
