## About "exercise" in BIP39

- "exercise" has 8 letters, but the first four, **"exer"**, already identify it, because **"exe"** also begins [execute](/bip39-word/execute/).
- **"exer"** is unique only within the English list: it also begins exercer in the [French list](/french/), so a four-letter backup should say which list it uses.
