About "valve" in BIP39

"valve" has 5 letters, but the first four, "valv", already identify it, because "val" also begins valid and valley.
The same spelling is in the French BIP39 wordlist, but as word #1971 (index 1970), not #1929. A wallet set to French reads "valve" as 11110110010 instead of 11110001000, and decodes index 1928 as "tropical".
"valv" is unique only within the English list: it also begins valvola in the Italian list, so a four-letter backup should say which list it uses.
"valve" appears in one of the 24 official English test vectors of BIP39: vector #22 (word 11 of 12). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
