Etymology: In Greek, "isos" means "equal" or "the same," and "onyma" means "name," so the combined term describes things that carry an identical name. The Greek adjective "isōnymos" is recorded in lexicons with this sense, but it was not a common word in classical writing. English "isonymous" is a modern technical adoption built from those classical parts. Its use is specialised, mainly in population studies, where researchers look at groups that share a surname. Because sharing a surname is a rough marker of common ancestry in many societies, the term became a way to describe that pattern. It is an example of how scholars draw on ancient roots to name concepts that did not exist in antiquity.
