A phrase is a group of words that lacks a subject, a verb, or both. If you punctuate a phrase as a sentence (with a capital letter and a period), you create a fragment.
Fragmented phrases are often prepositional phrases or verbal phrases; sometimes they are appositives, words or word groups that rename nouns or pronouns.
Fragmented phrases can be fixed in one of two ways:
A sentence can have a compound predicate, with two or more predicate phrases joined by a coordinating conjunction. Because the parts of a compound predicate have the same subject, they should appear in the same sentence.
The compound predicate is selects . . . and uses. . . . Notice that no comma appears between the two parts of a compound predicate.
