English has two main words spelled cock: the male bird, with its many mechanical and slang senses, and a small pile of hay.[1][2][3]

Pronunciation

  • IPA: /kɒk/ (UK); /kɑk/ (US)[4]

cock1 male bird; tap

Etymology

The bird is inherited from Old English cocc (“male bird”),[1][2][5][3] of imitative origin,[1][2][6] like Old Norse kokkr, Old French coc and Sanskrit कुक्कुट (kukkuṭa, “cock”);[1][2] Hoad derives the Old English word from Medieval Latin coccus, reinforced by French coq.[5] The native Germanic name survives in hen.[5][2]

Earliest recorded meaning

The male of the domestic fowl: about 897, in Alfred's translation of Gregory's Pastoral Care.[1][7]

Semantic evolution

Old English cocc was a nickname for one who strutted, and in the Middle Ages a cock was a pert boy or servant, then a fellow, as in old cock (1630s).[2][8] Technical senses, such as a tap (about 1425) and the hammer of a gun (1560s), are of uncertain connection with the bird;[1][2] German Hahn has the same range.[5][2] The verb, to fight (about 1150), led to the senses swagger (1575) and set or turn up jauntily (about 1600), as in cock one's ear.[1][2] To draw back the hammer of a gun is from the 1640s, and half-cocked by 1750.[2] The penis is a slang sense from the Middle Ages,[6] and Green notes that it became taboo in the 19th century.[8] A cock-and-bull story is from the 1620s.[2]

cock2 small heap of hay

Etymology

The haycock is of uncertain origin, probably related to dialectal German Kocke (“heap of hay or dung”) and Norwegian kok, heap.[1][3]

Earliest recorded meaning

A cone-shaped pile of hay in a field: before 1398, in Trevisa's translation of Bartholomew.[1]

Semantic evolution

The verb, to put hay into cocks, is probably from before 1387.[1]

Timeline

  • before 1387 – to put hay into cocks.[1]

Usage notes

A further obsolete cock, a small boat, survives only in cockboat and coxswain.[9] Green's Dictionary of Slang also records cock as a euphemism for God in oaths (about 1350).[8]
