About "chalk" in BIP39

"chalk" has 5 letters, but the first four, "chal", already identify it, because "cha" also begins 8 other words, among them chair, champion, change and chaos.
"chal" is unique only within the English list: it also begins chaleur in the French list, chaleco in the Spanish list, chaleira in the Portuguese list and chalupa in the Czech list, so a four-letter backup should say which list it uses.
