## About "captain" in BIP39

- "captain" has 7 letters, but the first four, **"capt"**, already identify it, because **"cap"** also begins [capable](/bip39-word/capable/) and [capital](/bip39-word/capital/).
- **"capt"** is unique only within the English list: it also begins capter in the [French list](/french/), captar in the [Spanish list](/spanish/) and captador in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
