Sentence fragments always make the list of the most common errors, and they are among the most seriously stigmatizing errors we can make. To put it simply, a sentence fragment is an incomplete sentence that you have punctuated as if it is a complete sentence.

Sometimes, fragments are missing a verb. Sometimes, fragments are missing a subject. Sometimes, a fragment is simply a dependent clause punctuated like a complete sentence. Here are some examples:

You’ll notice that each of these so-called sentences is not a complete sentence. They are both missing parts that would make them complete.

You always have options about how you correct a sentence fragment, but here are some possible corrections for our two sample sentence fragments:

Tips from the Professor

Fragments are among the most serious errors in academic writing. While you may read fiction and informal prose that contain sentence fragments, in academic writing, fragments are generally frowned upon. In fact, research on how errors are perceived by people indicates that fragments are what we call “status marking” errors, which means people will make negative assumptions about the intelligence of the writer when they see fragments in writing.

Of course, making a sentence fragment error has nothing to do with your intelligence. Usually, for native speakers of English, making a sentence fragment error is more about not editing carefully or just not being practiced in the rules.

In this video, the Grammar Professor will review what a fragment is and how you can avoid fragments in your academic writing.
