Definitions

3. Describing the phenomenon where two words share phonetic similarities while possessing different semantic properties in language usage

Etymology: The word comes from Greek "paronymos," built from "para," meaning "beside" or "alongside," and "onyma," meaning "name." Something paronymous was literally named beside something else, which is to say derived from the same root. That original sense is not the one most people use today. In older grammar, paronyms were related forms such as "grammar" and "grammatical," or "courage" and "courageous," that share a root but differ in function. Modern usage has narrowed toward words that look or sound alike but mean different things, such as "affect" and "effect." Dictionaries record both senses, so the term has shifted from a relationship of shared origin to one of surface resemblance.
