About "question" in BIP39
- "question" has 8 letters, but the first three, "que", already identify it, because "qu" also begins 7 other words, among them quality, quantum, quarter and quick. Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the French BIP39 wordlist, but as word #1581 (index 1580), not #1405. A wallet set to French reads "question" as 11000101100 instead of 10101111100, and decodes index 1404 as "outrager".
- "ques" is unique only within the English list: it also begins queso in the Spanish list, so a four-letter backup should say which list it uses.
