Diction (wrong word, ww)
Instructors use this term to mean that your word choice is not appropriate or does not make sense in the sentence. Such problems result when you don't really understand the material you're writing about or when you stretch for words with which you're not familiar. A good first step is to look up the word in a dictionary. If you find that diction is a problem, read your own paper aloud to yourself. Often, reading aloud helps you to hear problems that you don't see when you read it silently. If problems persist, ask a friend to read the paper, looking especially for words that don't seem to express the meaning you're after. Writing Center tutors can help as objective readers.
