About "length" in BIP39
- "length" has 6 letters, but the first four, "leng", already identify it, because "len" also begins lend and lens.
- "leng" is unique only within the English list: it also begins lengua in the Spanish list, so a four-letter backup should say which list it uses.
- "length" appears in one of the 24 official English test vectors of BIP39: vector #15 (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 #15, its final 8 bits, 00000000, are the checksum of the 24-word phrase.
