## About "master" in BIP39

- "master" has 6 letters, but the first four, **"mast"**, already identify it, because **"mas"** also begins [mask](/bip39-word/mask/) and [mass](/bip39-word/mass/).
- **"mast"** is unique only within the English list: it also begins mastino in the [Italian list](/italian/) and mastigar in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
