## About "accident" in BIP39

- "accident" has 8 letters, but the first four, **"acci"**, already identify it, because **"acc"** also begins [access](/bip39-word/access/), [account](/bip39-word/account/) and [accuse](/bip39-word/accuse/).
- **"acci"** is unique only within the English list: it also begins acción in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
