About "second" in BIP39
- "second" has 6 letters, but the first four, "seco", already identify it, because "sec" also begins secret, section and security.
- "seco" is unique only within the English list: it also begins secouer in the French list, seco in the Spanish list and secondo in the Italian list, so a four-letter backup should say which list it uses.
