## About "cruel" in BIP39

- "cruel" has 5 letters, but the first four, **"crue"**, already identify it, because **"cru"** also begins [crucial](/bip39-word/crucial/), [cruise](/bip39-word/cruise/), [crumble](/bip39-word/crumble/), [crunch](/bip39-word/crunch/) and [crush](/bip39-word/crush/).
- The same spelling is in the [French BIP39 wordlist](/french/), but as word #480 (index 479), not #421\. A wallet set to French reads "cruel" as **00111011111** instead of **00110100100**, and decodes index 420 as "coder".
