## About "special" in BIP39

- "special" has 7 letters, but the first four, **"spec"**, already identify it, because **"spe"** also begins [speak](/bip39-word/speak/), [speed](/bip39-word/speed/), [spell](/bip39-word/spell/) and [spend](/bip39-word/spend/).
- **"spec"** is unique only within the English list: it also begins specie in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
