Language is a communication system. It is true that we use language to communicate with others. However, language is much more than a communication system. The most recent thinking about the nature of language suggests that language is first and foremost a representational system; a system which provides us with the symbols we need to model for ourselves, to ourselves, inside our heads, the universe around us. This modeling, carried out using the symbols ("words") provided by language, is commonly called "thinking." The communication function of language, which allows us to represent things not only to ourselves but to others as well, is an added benefit.
