## About "language" in BIP39

- "language" has 8 letters, but the first three, **"lan"**, already identify it, because **"la"** also begins 19 other words, among them [lab](/bip39-word/lab/), [label](/bip39-word/label/), [labor](/bip39-word/labor/) and [ladder](/bip39-word/ladder/). Three letters are enough for only 604 of the 2048 words.
- **"lang"** is unique only within the English list: it also begins langage in the [French list](/french/) and langosta in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
