About "fantasy" in BIP39
- "fantasy" has 7 letters, but the first four, "fant", already identify it, because "fan" also begins fan and fancy.
- Its first letters also spell another BIP39 word, fan. Write "fantasy" out in full: cut short, it turns into a different valid word.
- "fant" is unique only within the English list: it also begins fantasma in the Italian list, fantoche in the Portuguese list and fantazie in the Czech list, so a four-letter backup should say which list it uses.
