Etymology

It is inherited from Middle English custumer, costomer,[2][3] borrowed from Anglo-Norman custumer, Old French coustumier,[2][4] from Medieval Latin custumārius (“toll-gatherer, tax collector”),[2][4] literally “pertaining to custom or customs”, a contraction of Latin consuetudinarius, from consuetudo “habit, usage, practice”,[2] the source of custom.[2][3] In some senses it was formed again in English from custom and -er.[4][3]

Earliest recorded meaning

A customs official, a toll-gatherer: the late 14th century in Etymonline,[2] 1448 in the OED.[5] The OED's first sense, about 1440, is a person who holds land by long custom.[5]

Semantic evolution

“One who buys goods, especially one who customarily buys from the same tradesman” is from about 1400 in Etymonline[2] and about 1480 in the OED.[5] Trench notes that two or three centuries before his time a customer was a collector of customs, as in Coverdale's “Levi the customer” for the tax collector of the Gospels.[6] The wider “person with whom one has dealings” is from the 1540s,[2] 1548 in the OED,[5] and the colloquial “person to deal with”, with an adjective as in an ugly customer, from the 1580s.[2][5] In Shakespeare it can also mean a prostitute.[2][5] In Scotland the customer was the lessee of a burgh's customs and dues.[7]
