Etymology: "Paronym" is a relatively recent coinage, dating from around 1846, built from classical Greek parts. The Greek adjective "parṓnumos" meant "derivative," formed from "para-," meaning "beside" or "alongside," and "-onym," from "onoma," the Greek word for "name." Literally, then, a paronym was a name standing beside another name, one that is closely related to it in form. The word was created to label a specific relationship among words: pairs or sets that sound or look alike but mean different things. English already had terms for related vocabulary, but this one picks out the near-miss, the similarity that is close enough to cause confusion. Its Greek core is shared with words like "synonym" and "antonym," which makes it sit comfortably in that family of coinages, though its meaning is about resemblance rather than sameness or opposition.
