trafficとは 意味・読み方・使い方

語源

From Middle French trafique, traffique (“traffic”), from Italian traffico (“traffic”) from trafficare (“to carry on trade”). Potentially from Vulgar Latin *trānsfrīcāre (“to rub across”); Klein instead suggests the Italian has ultimate origin in Arabic تَفْرِيق‎ (tafrīq, “distribution, dispersion”), reshaped to match the native prefix tra- (“trans-”).

The adjective sense is possibly influenced by Tagalog trapik and follows a general trend in Philippine English to make nouns adjectives.^[1]
