At its most basic level, a sentence contains a subject and a verb. So, what happens when we don't have a fully formed sentence? Or what if we have one that tries to cram in too much? That's exactly what we're going to talk about in this course: sentence fragments and run-on sentences. We'll learn about the different types of sentence fragments and the rare occasions when you might want to use them. We'll also learn about run-on sentences and how to avoid them.
