About "opinion" in BIP39
- "opinion" has 7 letters, but the first three, "opi", already identify it, because "op" also begins open, opera, oppose and option. Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the French BIP39 wordlist, but as word #1382 (index 1381), not #1244. A wallet set to French reads "opinion" as 10101100101 instead of 10011011011, and decodes index 1243 as "microbe".
- "opin" is unique only within the English list: it also begins opinar in the Spanish list and opinione in the Italian list, so a four-letter backup should say which list it uses.
