## About "chair" in BIP39

- "chair" has 5 letters, but the first four, **"chai"**, already identify it, because **"cha"** also begins 8 other words, among them [chalk](/bip39-word/chalk/), [champion](/bip39-word/champion/), [change](/bip39-word/change/) and [chaos](/bip39-word/chaos/).
- **"chai"** is unique only within the English list: it also begins chaise in the [French list](/french/), so a four-letter backup should say which list it uses.
