The word "偶像" is formed through a conceptual metaphor. It literally combines "偶", meaning a figurine or puppet (often one used in idolatry or ceremony), with "像", meaning an image, likeness, or portrait. Together, they create the idea of a "likeness in the form of an idol", directly translating to the English "idol". This term was historically used for religious statues but evolved to describe a person (like a celebrity or star) who is the object of intense admiration and devotion, metaphorically extending the idea of a crafted, worshiped image to a living person whose public persona is similarly elevated and revered.
