Summary:

This handout provides an overview and examples of sentence fragments.

Sentence Fragments

Fragments are incomplete sentences. Usually, fragments are pieces of sentences that have become disconnected from the main clause. One of the easiest ways to correct them is to remove the period between the fragment and the main clause. Other kinds of punctuation may be needed for the newly combined sentence.

Below are some examples with the fragments shown in red. Punctuation and/or words added to make corrections are highlighted in blue. Notice that the fragment is frequently a dependent clause or long phrase that follows the main clause.

You may have noticed that newspaper and magazine journalists often use a dependent clause as a separate sentence when it follows clearly from the preceding main clause, as in the last example above. This is a conventional journalistic practice, often used for emphasis. For academic writing and other more formal writing situations, however, you should avoid such journalistic fragment sentences.

Some fragments are not clearly pieces of sentences that have been left unattached to the main clause; they are written as main clauses but lack a subject or main verb.

No main verb

No Subject

These last three examples of fragments with no subjects are also known as mixed constructions, that is, sentences constructed out of mixed parts. They start one way (often with a long prepositional phrase) but end with a regular predicate. Usually the object of the preposition (often a gerund, as in the last two examples) is intended as the subject of the sentence, so removing the preposition at the beginning is usually the easiest way to edit such errors.
