## About "mystery" in BIP39

- "mystery" has 7 letters, but the first four, **"myst"**, already identify it, because **"mys"** also begins [myself](/bip39-word/myself/).
- **"myst"** is unique only within the English list: it also begins mystère in the [French list](/french/), so a four-letter backup should say which list it uses.
