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-”).


etymonline

traffic (n.)

c. 1500, "trade, commerce," from French trafique (15c.), from Italian traffico (14c.), from trafficare "carry on trade," of uncertain origin, perhaps from a Vulgar Latin *transfricare "to rub across," from Latin trans "across" (see trans-) + fricare "to rub" (see friction), with the original sense of the Italian verb being "touch repeatedly, handle."

Or the second element may be an unexplained alteration of Latin facere "to make, do." Klein suggests ultimate derivation of the Italian word from Arabic tafriq "distribution." Meaning "people and vehicles coming and going" first recorded 1825. Traffic jam is by 1908, ousting earlier traffic block (1895). Traffic circle is from 1938.




traffic (v.)

1540s, "to buy and sell," from traffic (n.) and preserving the original commercial sense. Related: Trafficked; trafficking; trafficker. The -k- is inserted to preserve the "k" sound of -c- before a suffix beginning in -i-, -y-, or -e- (compare picnic/picnicking, panic/panicky, shellacshellacked).
