metonym

n. word or concept that represents another word or concept to which it is related but does not specifically denote (Rhetoric)

In rhetoric, metonymy is the use of a word for a concept with which the original concept behind this word is associated. Metonymy may be instructively contrasted with metaphor. Both figures involve the substitution of one term for another. While in metaphor, this substitution is based on similarity, in metonymy the substitution is based on contiguity.
