Etymology: "Isonyms" is the plural of "isonym," a word formed from two Greek elements. The first, "is-", comes from Greek "isos," meaning "equal" or "same," the root that also gives English "isosceles" (equal sides) and "isotope." The second, "-onym," comes from Greek "onyma," meaning "name," and appears in "synonym" (same name) and "antonym" (opposite name). Put together, "isonym" means something like "same name," which is why it can be used for words that are spelled identically despite having different meanings or origins. The plural form simply applies the usual English rule for nouns ending in a consonant plus "-m" by adding "-s." Because the formation is transparent from its Greek parts, the term is best understood as a modern coinage built from classical building blocks rather than a word that came down from ancient usage.
