Etymology
The term 'bulls-eye' originated in the late 17th century, initially referring to the thick, circular glass pane used in ship decks, which was thought to resemble the eye of a bull. This literal, physical sense of a round, central object was then applied to the center of a target in archery and shooting by the early 18th century. The logic of the metaphor is clear: just as the bull's eye is a prominent, central feature, so too is the central spot of a target. From this concrete meaning, the term evolved abstractly in the 19th century to describe any action or remark that achieves its precise and intended goal, completing its journey from a physical descriptor to a metaphor for perfect accuracy.
Analysis
The compound "bulls-eye" is a lexicalized unit from English. Its components are the plural noun "bulls" and the noun "eye," but the combined meaning is not compositional from the modern senses of these words. It functions as a single semantic unit.
