## About "october" in BIP39

- "october" has 7 letters, but the first three, **"oct"**, already identify it, because **"oc"** also begins [occur](/bip39-word/occur/) and [ocean](/bip39-word/ocean/). Three letters are enough for only 604 of the 2048 words.
- **"octo"** is unique only within the English list: it also begins octobre in the [French list](/french/), so a four-letter backup should say which list it uses.
