About "mobile" in BIP39
- "mobile" has 6 letters, but the first three, "mob", already identify it, because "mo" also begins 20 other words, among them model, modify, mom and moment. Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the French BIP39 wordlist, but as word #1260 (index 1259), not #1140. A wallet set to French reads "mobile" as 10011101011 instead of 10001110011, and decodes index 1139 as "ligature".
- "mobi" is unique only within the English list: it also begins mobil in the Czech list, so a four-letter backup should say which list it uses.
