Like the majority of people, you probably learned the basic rules of grammar in school. And like the majority of people you’ve probably forgotten much of what you learned. Where does the comma go, for instance? Is ending your sentences with a preposition really that bad a practice? Are there hard and fast rules for when to use who, that or which? All of these questions, as well as many more, can plague both amateur and professional writers. Their online spelling and grammar checker assists you answering these questions and (hopefully) helps you to gain more confidence in your writing simultaneously. Student writings, of course, sometimes need the most proofreading. Teachers and instructors often expect student papers to be error-free, so it’s second nature to some of them to do spelling and grammar checks on all their papers. But many others get good use out of these tools: secretaries, job seekers, blog and article writers, or anyone who wants to make a good impression with their writing. It’s not unheard of for even professional writers to get into trouble with homonyms, words that sound alike but are spelled differently, or to get confused over comma placement. If you have access to a professional editor these little blips are not that important, but not many people have that access, which is why they are providing this online proofreading tool.
