Wouldn’t it be nice if you could just speak and write as you like, without having to learn the rules of grammar?

When you have something to express, you want to express it accurately, don’t you? You don’t want to be misunderstood. If everybody spoke and wrote perfect English, and everything you heard and read was expressed in perfect, accurate English, you probably wouldn’t have to study grammar! Grammar teaches you what corrections to make in your speech and writing and why the corrections should be made. And the study of grammar helps you improve the way you express yourself by using English which is accurate, clear, varied, and interesting.
