## About "course" in BIP39

- "course" has 6 letters, but the first four, **"cour"**, already identify it, because **"cou"** also begins [couch](/bip39-word/couch/), [country](/bip39-word/country/), [couple](/bip39-word/couple/) and [cousin](/bip39-word/cousin/).
- **"cour"** is unique only within the English list: it also begins courage in the [French list](/french/) and couro in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
