Synecdoche

Synecdoche (sɪˈnɛkdəki ) is a type of metonymy; it is a figure of speech in which a term for a part of something is used to refer to the whole (pars pro toto), or vice versa (totum pro parte). The term is derived . Examples of common English synecdoches include suits for businessmen, wheels for automobile, and boots for soldiers. Another example is the use of government buildings to refer to their resident agencies or bodies, such as The Pentagon for the United States Department of Defense and Downing Street or Number 10 for the office of the Prime Minister of the United Kingdom. Synecdoche is a rhetorical trope and a kind of metonymy—a figure of speech using a term to denote one thing to refer to a related thing. Synecdoche (and thus metonymy) is distinct from metaphor, although in the past, it was considered to be a sub-species of metaphor, intending metaphor as a type of conceptual substitution (as Quintilian does in Institutio oratoria Book VIII). In Lanham's Handlist of Rhetorical Terms, the three terms possess somewhat restrictive definitions in tune with their etymologies from Greek: Metaphor: changing a word from its literal meaning to one not properly applicable but analogous to it; assertion of identity—rather than likeness as with simile. Metonymy: substituting an attribute of or object associated with something for the thing itself (e.g., substituting "The crown" for "The monarch"). Synecdoche is often used as a type of personification by attaching a human aspect to a nonhuman thing. It is used in reference to political relations, including "having a footing", to mean a country or organization is in a position to act, or "the wrong hands", to describe opposing groups, usually in the context of military power. The two main types of synecdoche are microcosm and macrocosm. A microcosm uses a part of something to refer to the entirety. An example of this is saying "I need a hand" with a project, but needing the entire person. A macrocosm is the opposite, using the name of the entire structure of something to refer to a small part.
