Etymology: "Metonyms" is the plural of "metonym," a noun that names the device itself: a figure of speech in which one word stands in for something closely associated with it, as when "the crown" stands for a monarch. The singular "metonym" is a back-formation, meaning it was created by stripping an ending off a longer word, here the older term "metonymy." English speakers took "metonymy" as if it were a formation from a shorter base, then produced a new singular from it, so the word's ancestry runs backwards from the noun most people know. The longer word "metonymy" comes from Greek "metōnymia," built from "meta," meaning "change" or "after," and "onyma," meaning "name." Together the parts mean roughly "a change of name," which describes the device precisely: the name of one thing is transferred to another. The plural "metonyms" simply follows the regular English pattern for forming plurals of nouns ending in a consonant plus "-m" with an "-s."
