Synecdochical → It is formed from "synecdoche" (from Greek "synecdoche", meaning a figure of speech in which a part is made to represent the whole or vice versa) and the suffix "-ical" (meaning pertaining to). The word "synecdochical" refers to something that pertains to or is characteristic of the use of synecdoche in language.
