(i) The ideational function

　 When we use language to identify things, to think, or to record information, we use language as a symbolic code to represent the world around us. Playing this function, language serves as a medium that links a person with the world. Everything in mind exists through language. The ideational function is, then, the function language plays in human cognition, in our conceptualization of the world. It is this function of language, in a sense, that brings the world into our mind.
