Common Grammar and Punctuation Errors
What follows in this section are explanations of some of the most common grammar and punctuation errors. This is not meant to be an exhaustive list, but rather an overview of a few rules that seem to give student writers the most trouble. For a more complete list, consult an English language handbook or style manual. If you need additional explanation about a rule, consult a writing instructor or tutor on your campus.
Note: It is a good idea to become familiar with the rules of grammar that you violate most frequently so that you can begin to search for those particular errors when you edit your paper.
