chapman (n.): "peddler, itinerant tradesman," Middle English form of Old English ceapman "tradesman," from West Germanic compound *kaupman- (cognates: Old High German choufman, German Kauffman, Middle Dutch and Dutch koopman), formed with equivalents of man (n.) + West Germanic *kaup- (cognates: Old Saxon cop, Old Frisian kap "trade, purchase," Middle Dutch coop, Dutch koop "trade, market, bargain," kauf "trader," Old English ceap "barter, business; a purchase"), from Proto-Germanic *kaupoz- (cognates: Danish kj?b "purchase, bargain," Old Norse kaup "bargain, pay;" compare also Old Church Slavonic kupiti "to buy," a Germanic loan-word), probably an early Germanic borrowing from Latin caupo (genitive cauponis) "petty tradesman, huckster," which is of unknown origin. Compare also cheap (adj.).
