About "surprise" in BIP39
- "surprise" has 8 letters, but the first four, "surp", already identify it, because "sur" also begins sure, surface, surge, surround and survey.
- The same spelling is in the French BIP39 wordlist, but as word #1834 (index 1833), not #1748. A wallet set to French reads "surprise" as 11100101001 instead of 11011010011, and decodes index 1747 as "sensible".
- "surp" is unique only within the English list: it also begins surpresa in the Portuguese list, so a four-letter backup should say which list it uses.
