## About "diamond" in BIP39

- "diamond" has 7 letters, but the first four, **"diam"**, already identify it, because **"dia"** also begins [diagram](/bip39-word/diagram/), [dial](/bip39-word/dial/) and [diary](/bip39-word/diary/).
- **"diam"** is unique only within the English list: it also begins diamant in the [French list](/french/), diamante in the [Spanish list](/spanish/) and diametro in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
