## About "decade" in BIP39

- "decade" has 6 letters, but the first four, **"deca"**, already identify it, because **"dec"** also begins [december](/bip39-word/december/), [decide](/bip39-word/decide/), [decline](/bip39-word/decline/), [decorate](/bip39-word/decorate/) and [decrease](/bip39-word/decrease/).
- **"deca"** is unique only within the English list: it also begins decalque in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
