About "field" in BIP39

"field" has 5 letters, but the first three, "fie", already identify it, because "fi" also begins 19 other words, among them fiber, fiction, figure and file. Three letters are enough for only 604 of the 2048 words.
"fiel" is unique only within the English list: it also begins fiel in the Spanish list, so a four-letter backup should say which list it uses.
