As an instructor marks an essay, he or she will often note problems that appear in your writing. This guide presents brief explanations of common writing errors. However, the explanations are not designed to be comprehensive; they merely point out the most obvious features of the problems they describe. If you are not sure how to correct a specific problem, you may link to a more detailed grammar tutorial. If you need even more information, ask your instructor for help.
