The theme of linguistics is language, and the goal of linguistics is to understand more about language, in particular the nature of human language. Its missions in-clude, but not limited, to gain an understanding of what components constitute a human language, what principles govern language, what factors shape it, what makes it possible for humans to acquire language, and what relationship exists be-tween language and culture…etc. After the course overview and the introduction of the ideas of communication, four main sub-disciplinary subjects follow: pragmat-ics, semantics, syntax and morphology.
