1. A figure of speech in which a word or phrase that ordinarily designates one thing is used to designate another, thus making an implicit comparison, as in a sea of troubles or All the world's a stage (Shakespeare). 2. One thing conceived as representing another; a symbol: Hollywood has always been an irresistible, prefabricated metaphor for the crass, the materialistic, the shallow, and the craven (Neal Gabler, New York Times Book Review November 23, 1986).
