Mechanical issues such as grammatical errors can do more than just make your work appear sloppy: they can even change the meaning of your sentences, thereby confusing your reader. Thus, in the editing stage of the drafting process, it is important to polish your draft for grammatical mistakes and other “local” issues. While the principles discussed in this section are certainly not exhaustive, they address the most common grammatical mistakes found in student writing. Reviewing them in conjunction with other grammar rulebooks will provide you with the necessary tools to conclude your writing project with a clean, polished product.
