Metonymy

A metonymy is a figure of speech distinctly used to describe one entity that is representing another entity (such as using “head count” to mean "the number of people"). Metonymy differs from metaphor in that metonymy uses one entity to stand in for another, whereas metaphor uses one entity to describe another. Metonymy is seen as “a cognitive phenomenon underlying much of ordinary thinking.” The use of metonymy in language “is a reflection of its conceptual status,” since one conceptual entity is mentally accessed using another conceptual entity.
