It is through language that people gain understanding and come to know things, but the fact that something is true, will remain whether we come to know it or not. The answer to this question is not a god damn thing. The answer to this question is not a thing.
Language is nothing.
The only thing language does is communicate stuff which is impossible to truly express to another human. Language is nothing because it means nothing. Representations of things is all that language is. As a matter of fact I think I am going to start my own language. My own form of communication that only three people can understand.
