Linguistics is relevant to language teaching and learning, and to a wide range of professions. If you are learning a language, linguistics adds an extra dimension to your studies and broadens your outlook on language. It also goes together well with Psychology and Sociology. To study linguistics you don't have to have previous knowledge of any language other than English. In first year, the main language studied is English but we also draw on Aboriginal, Asian, European, and Pacific languages.
People study linguistics for many reasons.
You may be fascinated by the beauty and complexity of languages. Or perhaps you are interested in what makes us human, for language is probably the most distinctive human trait. Maybe you are learning or teaching a language, and want to do it better. Or you want to increase your understanding of culture or the social world. Because language is all-pervasive, linguistics has many practical applications.
