-onym Also -onymy, -onymic, and -onymous.
[Greek onuma, name.]
The ending principally appears in words that describe kinds of words. See the table below for some examples. Abstract nouns for the state or concept are formed in -onymy: homonymy, metonymy, toponymy. Adjectives are formed in -onymic or -onymous, sometimes both, though the former is rather more common (eponymous, metonymic, synonymous, toponymic).
