About "service" in BIP39

"service" has 7 letters, but the first four, "serv", already identify it, because "ser" also begins series.
The same spelling is in the French BIP39 wordlist, but as word #1757 (index 1756), not #1570. A wallet set to French reads "service" as 11011011100 instead of 11000100001, and decodes index 1569 as "puiser".
"serv" is unique only within the English list: it also begins servir in the Spanish list, servire in the Italian list, servo in the Portuguese list and servis in the Czech list, so a four-letter backup should say which list it uses.
