About "fatal" in BIP39
- "fatal" has 5 letters, but the first four, "fata", already identify it, because "fat" also begins fat, father and fatigue.
- Its first letters also spell another BIP39 word, fat. Write "fatal" out in full: cut short, it turns into a different valid word.
- The same spelling is in the French BIP39 wordlist, but as word #796 (index 795), not #669. A wallet set to French reads "fatal" as 01100011011 instead of 01010011100, and decodes index 668 as "enduire".
- "fatal" appears in one of the 24 official English test vectors of BIP39: vector #20 (word 12 of 18). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
