Grammar Syntax Questions
A phrase is a group of words that functions as a single unit within a sentence, but does not contain both a subject and a verb. It can act as a noun, verb, adjective, adverb, or preposition.
On the other hand, a clause is a group of words that contains both a subject and a verb and can function as a complete sentence (independent clause) or as a part of a sentence (dependent clause). Clauses can express a complete thought and can stand alone.
