Etymology

It is inherited from Middle English client, borrowed from Anglo-Norman clyent (1306),[2][3] and directly borrowed from Latin cliēns (“follower, retainer, dependant”).[3][2][4] The Latin word is usually explained as “one who leans on another”, related to clīnāre “to bend, incline”,[3][2][4] from Proto-Indo-European *klei- (“to lean”).[3] Hoad and the NODE instead take it as a variant of cluēns, the present participle of cluēre “to hear, obey”.[5][6] It is related to clientele and possibly to lean and incline.[2][3]

Earliest recorded meaning

One under the protection or patronage of another, a dependant: 1393 in the OED,[7] the late 14th century in Etymonline.[3] A lawyer's client is probably before 1387 in Barnhart, in Piers Plowman,[2] and 1413 in the OED.[7]

Semantic evolution

In ancient Rome a client was a plebeian under the protection of a patrician, his patronus;[3][7] in medieval English the word reflected the feudal hierarchy of dependants.[8] The lawyer's client came from French use.[8] From about 1600 the word was extended to anyone who employs a professional or business person, a customer (1608, in Shakespeare's Pericles).[2][3][7] A person helped by a social worker is from 1925,[7] and a client state, dependent on a larger power, from 1919.[7] In computing, a client is a program or machine that receives services from a server.[9]
