About "chapter" in BIP39
- "chapter" has 7 letters, but the first four, "chap", already identify it, because "cha" also begins 8 other words, among them chair, chalk, champion and change.
- "chap" is unique only within the English list: it also begins chapitre in the French list, chapa in the Spanish list, chapada in the Portuguese list and chapadlo in the Czech list, so a four-letter backup should say which list it uses.
