About "fatigue" in BIP39
- "fatigue" has 7 letters, but the first four, "fati", already identify it, because "fat" also begins fat, fatal and father.
- Its first letters also spell another BIP39 word, fat. Write "fatigue" out in full: cut short, it turns into a different valid word.
- The same spelling is in the French BIP39 wordlist, but as word #797 (index 796), not #671. A wallet set to French reads "fatigue" as 01100011100 instead of 01010011110, and decodes index 670 as "enfance".
- "fati" is unique only within the English list: it also begins fatiga in the Spanish list, faticare in the Italian list and fatia in the Portuguese list, so a four-letter backup should say which list it uses.
