Metonymy (/mɪˈtɒnɪmi, mɛ-/) is a figure of speech in which a concept is referred to by the name of something associated with that thing or concept. For example, the word "suit" may refer to a person from groups commonly wearing business attire, such as business executives, bankers or attorneys.
Metonymies are common in everyday speech and encapsulate a range of other ideas, such as synecdoche and metalepsis. Metonymies are similar to metaphors but where metaphors rely on analogous characteristics to form a comparison, a metonymy is caused by general association of the two objects of comparison.
