At the Writing Center, we see A LOT of sentence fragments. These are logical strings of words that begin with a capital letter and end with a period, but unbeknownst to our writers, are not actually full sentences. Another way to refer to these sentence fragments is as "dependent clauses."

Check out this site for a clear and concise explanation of independent and dependent clauses and protect yourself from ever making this mistake!
