## About "occur" in BIP39

- "occur" has 5 letters, but the first three, **"occ"**, already identify it, because **"oc"** also begins [ocean](/bip39-word/ocean/) and [october](/bip39-word/october/). Three letters are enough for only 604 of the 2048 words.
- **"occu"** is unique only within the English list: it also begins occuper in the [French list](/french/) and occultare in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
