A fragment sentence is a sentence that is incomplete and does not express a complete thought. It has a subject and a predicate, but it is missing a main clause. Most of the time, a fragment is the result of a misplaced period that separates certain words or information from a sentence’s main clause. You can recognize this kind of fragment by paying attention to the first word in the phrase. ^{gcfglobal.org}+1 ^{1 2}
