Frequently Made Mistakes in Grammar and Mechanics

Fragments

Fragments are incomplete sentences that are missing a subject, a verb, or both, and are punctuated as if they were complete sentences. 

  • You always need a subject and a verb to make a complete sentence.
    • In this example, But had no money has no subject. 
      • WRONG:   I was trying to register for school last week.  But had no money.
    • You can fix the problem by joining the two sentences with a comma and adding the subject I.
      • CORRECT:   I was trying to register for school last week, but I had no money.
    • In this example, the main verb is missing.
      • WRONG:  The lab the most problematic section of the Biology course.
    • You can fix the problem by adding a verb to complete the subject-verb agreement.
      • CORRECT:  The lab was the most problematic section of the Biology course.
