## About "obscure" in BIP39

- "obscure" has 7 letters, but the first four, **"obsc"**, already identify it, because **"obs"** also begins [observe](/bip39-word/observe/).
- **"obsc"** is unique only within the English list: it also begins obscur in the [French list](/french/) and obscuro in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
