Revising for grammar and mechanics, often called editing or proofreading, takes time, but it is time well spent. Editing helps you create a finished work that represents your best efforts. Consider this: Readers don’t notice correct spelling, but they do notice misspellings. Readers don’t cheer when you use “there,” “their,” and “they’re” correctly, but they notice when you don’t. Readers rarely marvel at the construction of a complete sentence, but they will be confused and irritated by fragments and run-ons. If you revise for grammar and mechanics, readers will notice your attention to detail in the delivery of an error-free document.
