## About "actor" in BIP39

- "actor" has 5 letters, but the first four, **"acto"**, already identify it, because **"act"** also begins [act](/bip39-word/act/), [action](/bip39-word/action/), [actress](/bip39-word/actress/) and [actual](/bip39-word/actual/).
- Its first letters also spell another BIP39 word, [act](/bip39-word/act/). Write "actor" out in full: cut short, it turns into a different valid word.
- **"acto"** is unique only within the English list: it also begins acto in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
