4. How Do You Correct a Missing Subject or Missing Verb Fragment? If a fragment is missing a subject, a verb, or both, you can correct it by adding the missing elements. Sometimes, the missing elements may be in the sentence preceding or following the fragment. In these situations, you could correct the fragment by joining it to the sentence where it belongs. The following boxes provide examples of these two methods of correcting fragments. Correct by Adding Missing Parts Fragment: Missing Element: Complete Sentence: Took a long nap a subject The toddler took a long nap. Fragment: Correct by Joining to Sentence Missing Elements: Complete Sentence: The toddler napped. From noon until 2:00 PM a subject and a verb The toddler napped from noon until 2:00 PM. In the first example, the group of words Took a long nap is a fragment because the reader doesn't know who or what took a nap. The fragment becomes a complete sentence by adding a subject, The toddler. In the second example, the prepositional phrase from noon until 2:00 PM is a fragment; prepositional phrases never function as the subject or a verb of a sentence. The fragment becomes a complete sentence when it is joined with the preceding sentence, The toddler napped.
