About "action" in BIP39
- "action" has 6 letters, but the first four, "acti", already identify it, because "act" also begins act, actor, actress and actual.
- Its first letters also spell another BIP39 word, act. Write "action" out in full: cut short, it turns into a different valid word.
- "acti" is unique only within the English list: it also begins actif in the French list and activo in the Spanish list, so a four-letter backup should say which list it uses.
