## About "decide" in BIP39

- "decide" has 6 letters, but the first four, **"deci"**, already identify it, because **"dec"** also begins [decade](/bip39-word/decade/), [december](/bip39-word/december/), [decline](/bip39-word/decline/), [decorate](/bip39-word/decorate/) and [decrease](/bip39-word/decrease/).
- **"deci"** is unique only within the English list: it also begins decir in the [Spanish list](/spanish/), deciso in the [Italian list](/italian/), decimal in the [Portuguese list](/portuguese/) and decibel in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
