About "express" in BIP39
- "express" has 7 letters, but the first four, "expr", already identify it, because "exp" also begins expand, expect, expire, explain and expose.
- "expr" is unique only within the English list: it also begins exprimer in the French list and expresso in the Portuguese list, so a four-letter backup should say which list it uses.
