## About "expect" in BIP39

- "expect" has 6 letters, but the first four, **"expe"**, already identify it, because **"exp"** also begins [expand](/bip39-word/expand/), [expire](/bip39-word/expire/), [explain](/bip39-word/explain/), [expose](/bip39-word/expose/) and [express](/bip39-word/express/).
- **"expe"** is unique only within the English list: it also begins experto in the [Spanish list](/spanish/), expelir in the [Portuguese list](/portuguese/) and expedice in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
