About "spell" in BIP39
- "spell" has 5 letters, but the first four, "spel", already identify it, because "spe" also begins speak, special, speed and spend.
- "spel" is unique only within the English list: it also begins spelatura in the Italian list, so a four-letter backup should say which list it uses.
- "spell" appears in one of the 24 official English test vectors of BIP39: vector #17 (word 6 of 18). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
