## About "monster" in BIP39

- "monster" has 7 letters, but the first four, **"mons"**, already identify it, because **"mon"** also begins [monitor](/bip39-word/monitor/), [monkey](/bip39-word/monkey/) and [month](/bip39-word/month/).
- **"mons"** is unique only within the English list: it also begins monstre in the [French list](/french/), monsone in the [Italian list](/italian/) and monstrum in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
