What does lookalike mean?
A lookalike is a person or thing that closely resembles another in appearance. The term most often describes someone whose face, build, or overall appearance is strikingly similar to that of a well-known or familiar person, but it can also refer to objects, images, or products that seem nearly identical to something else. In conversation, "lookalike" often carries the implication of a striking resemblance rather than a casual similarity. It can be used respectfully, humorously, or as a warning about imitation and deception. When referring to a person, the word distinguishes appearance from identity: a lookalike may look like someone else without sharing that person's background, personality, or life. In product contexts, it often helps identify counterfeit or imitation goods, although the expression can also be used neutrally for objects that simply have a very similar design.

Where does lookalike come from?
The word was formed in the 20th century by combining "look" with "alike," meaning "similar in appearance." Both elements reflect broad Germanic roots associated with observing appearance and likeness. The compound became especially useful for describing people who resemble public figures, while later usage extended it to similar-looking objects, images, and products.
