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]
