## About "define" in BIP39

- "define" has 6 letters, but the first four, **"defi"**, already identify it, because **"def"** also begins [defense](/bip39-word/defense/) and [defy](/bip39-word/defy/).
- **"defi"** is unique only within the English list: it also begins definir in the [Spanish list](/spanish/), definito in the [Italian list](/italian/) and deficit in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
