About "impact" in BIP39
- "impact" has 6 letters, but the first four, "impa", already identify it, because "imp" also begins impose, improve and impulse.
- The same spelling is in the French BIP39 wordlist, but as word #1018 (index 1017), not #911. A wallet set to French reads "impact" as 01111111001 instead of 01110001110, and decodes index 910 as "gestuel".
- "impa" is unique only within the English list: it also begins impar in the Spanish list, impacco in the Italian list and impacto in the Portuguese list, so a four-letter backup should say which list it uses.
