About "piano" in BIP39
- "piano" has 5 letters, but the first three, "pia", already identify it, because "pi" also begins 13 other words, among them picnic, picture, piece and pig. Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the French BIP39 wordlist, but as word #1479 (index 1478), not #1313. A wallet set to French reads "piano" as 10111000110 instead of 10100100000, and decodes index 1312 as "neige".
- "pian" is unique only within the English list: it also begins pianta in the Italian list and pianista in the Czech list, so a four-letter backup should say which list it uses.
