About "tumble" in BIP39
- "tumble" has 6 letters, but the first three, "tum", already identify it, because "tu" also begins 7 other words, among them tube, tuition, tuna and tunnel. Three letters are enough for only 604 of the 2048 words.
- "tumb" is unique only within the English list: it also begins tumba in the Spanish list, so a four-letter backup should say which list it uses.
