About "used" in BIP39
- It takes all four letters to identify "used": "use" also begins use, useful and useless.
- Its first letters also spell another BIP39 word, use. Write "used" out in full: cut short, it turns into a different valid word.
- "used" is unique only within the English list: it also begins usednout in the Czech list, so a four-letter backup should say which list it uses.
