About "sponsor" in BIP39
- "sponsor" has 7 letters, but the first four, "spon", already identify it, because "spo" also begins spoil, spoon, sport and spot.
- "spon" is unique only within the English list: it also begins sponzor in the Czech list, so a four-letter backup should say which list it uses.
- "sponsor" appears in one of the 24 official English test vectors of BIP39: vector #17 (word 5 of 18). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
