## About "mouse" in BIP39

- "mouse" has 5 letters, but the first four, **"mous"**, already identify it, because **"mou"** also begins [mountain](/bip39-word/mountain/).
- **"mous"** is unique only within the English list: it also begins mousson in the [French list](/french/), so a four-letter backup should say which list it uses.
