## About "horror" in BIP39

- "horror" has 6 letters, but the first four, **"horr"**, already identify it, because **"hor"** also begins [horn](/bip39-word/horn/) and [horse](/bip39-word/horse/).
- **"horr"** is unique only within the English list: it also begins horrible in the [French list](/french/), so a four-letter backup should say which list it uses.
