About "space" in BIP39
- "space" has 5 letters, but the first four, "spac", already identify it, because "spa" also begins spare, spatial and spawn.
- "spac" is unique only within the English list: it also begins spacieux in the French list, so a four-letter backup should say which list it uses.
- "space" appears in one of the 24 official English test vectors of BIP39: vector #24 (word 18 of 24). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
