## About "decline" in BIP39

- "decline" has 7 letters, but the first four, **"decl"**, already identify it, because **"dec"** also begins [decade](/bip39-word/decade/), [december](/bip39-word/december/), [decide](/bip39-word/decide/), [decorate](/bip39-word/decorate/) and [decrease](/bip39-word/decrease/).
- **"decl"** is unique only within the English list: it also begins declino in the [Italian list](/italian/) and declive in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
