About "cost" in BIP39
- "cost" has 4 letters, but the first three, "cos", already identify it, because "co" also begins 40 other words, among them coach, coast, coconut and code. Three letters are enough for only 604 of the 2048 words.
- "cost" is unique only within the English list: it also begins costume in the French list, costa in the Spanish list, costante in the Italian list and costela in the Portuguese list, so a four-letter backup should say which list it uses.
