Idioms

From Fresh Dictionary

Wiktionary also functions as a basic idiom dictionary, including stock phrases, metaphors, fictional characters, etc. Explaining these and their significance often requires far more than a simple defining vocabulary. Wiktionary's role is to explain the linguistic importance, the origin, and usage of these terms. Much broader and more detailed contexts will often be the function of Wikipedia.

Some thesaurus considerations apply to idiom dictionary use.

An idiom may be one word, but for practical purposes entries for idioms in Wiktionary refer to expressions containing two or more words.
