What is the difference between a phrase and a clause?

A phrase is a group of words that functions as a single unit within a sentence, but does not contain a subject and a verb. It can act as a noun, adjective, or adverb. On the other hand, a clause is a group of words that contains a subject and a verb and can function as a complete sentence or as part of a sentence. Clauses can be independent (also known as main clauses) or dependent (also known as subordinate clauses).
