Fragments can be difficult to identify because they blend into the writing. One useful trick is to begin at the end of the essay and read one sentence at a time working backward. This tends to make the fragments stand out from the surrounding text. Some common problems are fragments using a gerund or participle (words ending in -ing like "saying") or dependent clause fragments (clauses beginning with words like "because" or "which"). Once students have identified what kind of fragments they most commonly make, they can look for the same pattern as they proofread.
Hint: The word which (and, in most cases, the word who) will never begin a sentence unless that sentence is a question.
Which way did he go? (Sentence)
Which is how I found him. (Fragment)
Who is following you? (Sentence)
Who walked me home after the dance. (Fragment)
Who walked me home after the dance is none of your business. (Sentence: Here the clause Who walked me home after the dance is a noun clause serving as the subject of the sentence.)
