Capítulo 1: welcome to English- What us grammer?

let's get going, what is grrammer? will gramaeis a set of rules that you will have to apply while speaking English. But did you know that you already know all the rules? or maybe some, but thats not the point. Everything your speaking your using grammar it might just be the fact that you don't know your using it. More important, you don't know what there called. And that brings me to my second point witch is that those rules are in categories. Examples? I bet you've heard the word noun. And its totally ok if you haven't. but thats what grammer is.
