## About "utility" in BIP39

- Two letters are enough: no other BIP39 word begins with **"ut"**, which makes "utility" one of only 34 words that can be told apart this early.
- **"util"** is unique only within the English list: it also begins utile in the [French list](/french/) and utilizzo in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
