About "farm" in BIP39
- "farm" has 4 letters, but the first three, "far", already identify it, because "fa" also begins 21 other words, among them fabric, face, faculty and fade. Three letters are enough for only 604 of the 2048 words.
- "farm" is unique only within the English list: it also begins farmacia in the Spanish list, farmaco in the Italian list and farmacie in the Czech list, so a four-letter backup should say which list it uses.
