IDIOM
An "idiom" is a phrase that has a specific meaning, different than you would expect based on the individual words.
Idiom is more subtle. It can be informal or merely non-literal, and either a phrase or a complete sentence.

Here's the subtle part: It requires an idiomatic understanding of language to use these non-obvious forms of speech correctly. Idioms resemble metaphors, but are more general.
PHRASE

- "Phrase" can really describe any collection of words.
A phrase is “a small group of words standing together as a conceptual unit”, while an idiom is “a group of words established by usage as having a meaning not deducible from those of the individual words”. So, the difference is that an idiom as an established meaning not directly linked to the individual words. Any idiom is a phrase.
As an example, “raining cats and dogs” is both an idiom and a phrase. “A herd of cats” is a phrase but not an idiom.
