## About "bachelor" in BIP39

- "bachelor" has 8 letters, but the first four, **"bach"**, already identify it, because **"bac"** also begins [bacon](/bip39-word/bacon/).
- **"bach"** is unique only within the English list: it also begins bache in the [Spanish list](/spanish/), bacharel in the [Portuguese list](/portuguese/) and bachor in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
