| 词汇 | traffic |
| 词根词缀 | 词源： traffic (n.) 1505, "trade, commerce," from M.Fr. trafique (1441), from It. traffico (1323), from trafficare "carry on trade," of uncertain origin, perhaps from a V.L. *transfricare "to rub across" (from L. trans- "across" + fricare "to rub"), with the original sense of the It. verb being "touch repeatedly, handle." Or the second element may be an unexplained alteration of L. facere "to make, do." Klein suggests ultimate derivation of the It. word from Arabic tafriq "distribution." Meaning "people and vehicles coming and going" first recorded 1825. The verb is from 1542 (and preserves the original commercial sense). Traffic jam is 1917, ousting earlier traffic block (1895). 词根记忆： n. 交通,交通量Traffic is very heavy during the rush hour.尖峰时间交通十分繁忙. |
