Language is the method in which humans communicate, but it is also the system that allows us to process reality. Language can help us <em>define</em> the things we see by creating categories and qualities that things have or not have. It can also <em>influence</em> when being used to persuade, educate or indoctrinate people. Language <em>reflects</em> experience, as we name the things we see and feel. Finally, language can <em>describe</em>, in order to make our experience clearer or richer.
