## About "brass" in BIP39

- "brass" has 5 letters, but the first four, **"bras"**, already identify it, because **"bra"** also begins [bracket](/bip39-word/bracket/), [brain](/bip39-word/brain/), [brand](/bip39-word/brand/) and [brave](/bip39-word/brave/).
- **"bras"** is unique only within the English list: it also begins brasier in the [French list](/french/) and brasa in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
