## About "sign" in BIP39

- It takes all four letters to identify "sign": **"sig"** also begins [sight](/bip39-word/sight/).
- **"sign"** is unique only within the English list: it also begins signal in the [French list](/french/), signo in the [Spanish list](/spanish/) and signore in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
