Etymology

It is Middle English compleinen, borrowed from Old French complaign- (“to lament”), the stem of complaindre,[2][3][4] from Vulgar Latin *complangere (“to beat the breast”), from com-, intensive, and plangere (“to strike, lament”) (see plaint),[2][3][4] from PIE Proto-Indo-European *plak- (“to strike”).[3]

Earliest recorded meaning

To find fault or accuse: about 1370, in Chaucer, in Barnhart;[2] to lament or bewail, about 1374 in the OED and about 1375 in Barnhart.[5][2]

Semantic evolution

Etymonline traces the development from expressing suffering to expressing a grievance or blame.[3] The transitive sense, to lament something, died out in the 17th century.[3][5] Making a formal accusation to an authority is from the late 14th century.[3] To report pain or illness, as in complain of headaches, is from 1607,[5] and, chiefly in poetry, to make a mournful sound from the 1690s.[3] Complaint is from about 1380.[2]
