Pars pro toto

Latin for a part (taken) for the whole

Pars pro toto, is a figure of speech where the name of a portion of an object, place, or concept is used or taken to represent its entirety. It is distinct from a merism, which is a reference to a whole by an enumeration of parts; metonymy, where an object, place, or concept is called by something or some place associated with it; or synecdoche, which can refer both to pars pro toto and its inverse, totum pro parte.
