About "track" in BIP39

"track" has 5 letters, but the first four, "trac", already identify it, because "tra" also begins 9 other words, among them trade, traffic, tragic and train.
"trac" is unique only within the English list: it also begins traction in the French list, tractor in the Spanish list, trachea in the Italian list and tracejar in the Portuguese list, so a four-letter backup should say which list it uses.
