About "reform" in BIP39
- "reform" has 6 letters, but the first four, "refo", already identify it, because "ref" also begins reflect and refuse.
- "refo" is unique only within the English list: it also begins reforma in the Spanish list and refogar in the Portuguese list, so a four-letter backup should say which list it uses.
- "reform" appears in one of the 24 official English test vectors of BIP39: vector #21 (word 24 of 24). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words. As the last word of vector #21, its final 8 bits, 10100010, are the checksum of the 24-word phrase.
