Etymology: < classical Latin -ōnymia ( < Hellenistic Greek -ωνυμία (in ὁμωνυμία verbal identity (see homonymy n.), μετωνυμία metonymy n., etc.) < ancient Greek (Doric and Aeolic) ὄνυμα name, word (see -onym comb. form) + -ια -y suffix3. Compare French -onymie.Combined with first elements ultimately of Greek origin. Earliest attested in metonymy n., the proximate source of which is Latin. The proximate source of several other early formations is French (compare homonymy n.). -onymy occurs in a large number of formations from the late 19th and early 20th cent., a number of which are native formations in English, as myonymy n. at myo- comb. form , micronymy n., etc. Occasionally forms in -onomy (compare forms s.vv. organonymy n., toponymy n.) are probably after ancient Greek (Attic) ὄνομα (see onomato- comb. form).
