SYNECDOCHE — [Noun] A figure of speech in which a part stands for the whole, the whole for a part, or a specific instance for a general category. From the Latin synecdochē, from Ancient Greek συνεκδοχή (sunekdokhḗ, "receiving together"), from σύν (sún, "with") + ἐκ (ek, "out of") + δέχεσθαι (dékhesthai, "to accept"), related to δοκέω (dokéō, "to think, suppose, seem"). Unlike "metonymy" (which trades one concept for another by association) or "hyperbole" (which inflates for effect), synecdoche is a quiet sleight of hand, a compression of meaning. It is the gleam of a single headlight in the dark standing in for the whole approaching car, the rustle of "a hundred sails" conjuring an entire fleet, or the way we speak of "lending a hand" when what we mean is the full weight of a person’s presence. In synecdoche, the world contracts and expands at once: every part contains the whole, and every whole is haunted by its missing pieces.
