for writers and readers….
If you get the rhythm of your writing right, the other things tend to fall into place. Most people know the grammatical rules of writing more than they think they do. You probably know where the subject and verb should go in a sentence, even if you can’t identify them. (Most people can’t.) You know the subject and verb go at that point in the sentence, and in that order, because it sounds right. If it sounds right, it’s probably grammatically right; if it sounds wrong, it’s probably grammatically wrong. You should certainly trust your ear more than the grammar check on MS Word, which is pretty useless.
