About "crucial" in BIP39
- "crucial" has 7 letters, but the first four, "cruc", already identify it, because "cru" also begins cruel, cruise, crumble, crunch and crush.
- The same spelling is in the French BIP39 wordlist, but as word #479 (index 478), not #420. A wallet set to French reads "crucial" as 00111011110 instead of 00110100011, and decodes index 419 as "cocotier".
- "cruc" is unique only within the English list: it also begins cruciale in the Italian list, so a four-letter backup should say which list it uses.
