## About "false" in BIP39

- "false" has 5 letters, but the first four, **"fals"**, already identify it, because **"fal"** also begins [fall](/bip39-word/fall/).
- **"fals"** is unique only within the English list: it also begins falso in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
