## About "tortoise" in BIP39

- "tortoise" has 8 letters, but the first four, **"tort"**, already identify it, because **"tor"** also begins [torch](/bip39-word/torch/) and [tornado](/bip39-word/tornado/).
- **"tort"** is unique only within the English list: it also begins tortue in the [French list](/french/), tortuga in the [Spanish list](/spanish/), tortora in the [Italian list](/italian/) and torto in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
