-onym
（重定向自Andronym）
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.
