Why we still need grammar？

The first reason is that grammardoes have a role in language teaching. It is not something that we are completely unconscious. 

The second reason why we need grammar is when we are learning a language as grown-up. It’s that grammar gives us a short cut to learning. It’s a quick way to understanding something.

The third reason why we learn grammar is that it’s expected. In other words it is unimaginable that we would do a language and no thave any grammar. If we don’t have any grammar, all the mistakes we make will become a habit. And we will learn to form very very bad habits in the way we express ourselves, because no one could correct that.”
