Unlike other rhyming dictionaries, Rhymesaurus FREE Edition doesn't just give you a list of words that rhyme with your word, it also includes idioms, phrases, and cliches in the results. For example, type in "cat" and you not only get the rhyming words, such as "bat," "format," "habitat," and "aristocrat," you also get phrases such as "at the drop of a hat," "chew the fat," "stand pat," "smell a rat," and so on.

Having idioms, phrases, and cliches in the results is helpful as it quickly shows you many different ways in which the rhyme words are commonly used.
