## About "second" in BIP39

- "second" has 6 letters, but the first four, **"seco"**, already identify it, because **"sec"** also begins [secret](/bip39-word/secret/), [section](/bip39-word/section/) and [security](/bip39-word/security/).
- **"seco"** is unique only within the English list: it also begins secouer in the [French list](/french/), seco in the [Spanish list](/spanish/) and secondo in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
