Etymology
The term 'bull's-eye' originated in the late 17th century, initially referring to a thick disc of glass set into a ship's deck or side to admit light. The connection to archery or shooting targets is believed to be a later metaphorical development. One theory suggests the name for the glass pane came from its resemblance to a bull's eye, while another posits a direct link to the target's center, perhaps humorously comparing it to the small, focused eye of a bull. Over time, the primary meaning shifted to the target's center, and from there, it broadened into a general metaphor for any precise and successful achievement.
Analysis
This is a compound noun formed from the genitive form of 'bull' and the word 'eye'. 'Bull' is from Old English bula (male bovine). 'Eye' is from Old English ēage (organ of sight).
