What are phrases?

A phrase is a group of words, without a subject or a verb. It cannot stand alone as an independent unit. A phrase can function only as a part of speech. There are several different kinds of phrases, including prepositional phrases (with the subcategories adjectival phrases and adverbial phrases), appositives, and verbal phrases.
