The
suffix -onym, in
English and other languages, means "word, name", and
words ending in
-onym refer to a specified kind of name or word, most of which are
classical compounds. For example, an
acronym is a word formed from the initial letter or letters of each of the successive parts or major parts of a compound term (as
radar). The use of
-onym words provides a means of classifying, often to a fine degree of resolution, sets of nouns with common attributes.
