Fragments are incomplete sentences. Some fragments are obviously related to the sentences before or after them. Therefore, a fragment is often next to the sentence it should join, and one of the easiest ways to correct a fragment is to connect it to a nearby whole sentence.
For example:
Northern offers many majors in English. Such as writing, education, and graduate bound.
Revision:
Northern offers many majors in English, such as writing, education, and graduate bound.
For example:
I need to find a new friend. Because the one I have now is mean.
Revision:
I need to find a new friend because the one I have now is mean.
OR
I need to find a new friend. The one I have now is mean.
Some fragments are not clearly parts of sentences. These often lack a subject or a verb. Both a subject and a verb are necessary to make up a complete sentence.
For example:
A story with deep thought and emotion. (no main verb)
Revision:
She told a story with deep thought and emotion. OR A story with deep thought and emotion would be best right now.
For example:
Walking softly through the night. (no subject)
Revision:
She went on walking softly through the night. OR She walked softly through the night.
To spot fragments: Watch for sentences that lack either a subject or a verb.
