## About "unhappy" in BIP39

- "unhappy" has 7 letters, but the first three, **"unh"**, already identify it, because **"un"** also begins 17 other words, among them [unable](/bip39-word/unable/), [unaware](/bip39-word/unaware/), [uncle](/bip39-word/uncle/) and [uncover](/bip39-word/uncover/). Three letters are enough for only 604 of the 2048 words.
- **"unha"** is unique only within the English list: it also begins unha in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
