mid-12c., cocken, "to fight;" 1570s, "to swagger;" 1640s as "to raise or draw back the hammer or cock of a gun or pistol as a preliminary to firing." Seeming contradictory modern senses of "to turn or stand up, turn to one side" (as in cock one's ear), c. 1600, and "to bend" (1898) are from the two cock nouns. The first is probably in reference to the posture of the bird's head or tail, the second to the firearm position.

To go off half-cocked in the figurative sense "speak or act too hastily" (1833) is in allusion to firearms going off unexpectedly when supposedly secure; half-cocked in a literal sense "with the cock lifted to the first catch, at which position the trigger does not act" is recorded by 1750. In 1770 it was noted as a synonym for "drunk."
c. 1200, from Old English ege (Mercian), eage (West Saxon) "eye; region around the eye; apperture, hole," from Proto-Germanic *augon (source also of Old Saxon aga, Old Frisian age, Old Norse auga, Swedish öga, Danish øie, Middle Dutch oghe, Dutch oog, Old High German ouga, German Auge, Gothic augo "eye"). Apparently the Germanic form evolved irregularly from PIE root *okw- "to see."
