About "across" in BIP39
- "across" has 6 letters, but the first three, "acr", already identify it, because "ac" also begins 13 other words, among them access, accident, account and accuse. Three letters are enough for only 604 of the 2048 words.
- "acro" is unique only within the English list: it also begins acronyme in the French list and acrobata in the Italian list, so a four-letter backup should say which list it uses.
