## About "diary" in BIP39

- "diary" has 5 letters, but the first four, **"diar"**, already identify it, because **"dia"** also begins [diagram](/bip39-word/diagram/), [dial](/bip39-word/dial/) and [diamond](/bip39-word/diamond/).
- **"diar"** is unique only within the English list: it also begins diario in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
