Except for a command with an implied or understood subject, a word group punctuated as a sentence without a subject is a sentence fragment. Example: Michelle came into the room. Closed the door. How to: Include an appropriate subject to form an independent clause. Correction: Michelle came into the room. She closed the door.

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.
