Students interested in the study of science, language, and cultures would enjoy this academic discipline. Linguists study human languages across cultures in a scientific light. The field can be subdivided into different areas of interest. A few examples include evolutionary, historical, applied, neurological and psychological linguistics, but all linguists are interested in the grammar, meaning and the contextual use of words in different languages. Linguists are needed in a diverse range of industries because of their unique understanding of human languages and communication.
