About "option" in BIP39
- "option" has 6 letters, but the first three, "opt", already identify it, because "op" also begins open, opera, opinion and oppose. Three letters are enough for only 604 of the 2048 words.
- "opti" is unique only within the English list: it also begins optique in the French list, so a four-letter backup should say which list it uses.
