Linguistics is the study of language. The document outlines four major views of language: structuralism, transformationalism, functionalism, and interactionalism. Structuralism views language as a system of observable elements like sounds, words and sentences. Transformationalism sees language as innate and universal, governed by an innate language acquisition device. Functionalism emphasizes the meaning and functions of language in communication. Interactionalism considers language a tool for social interactions and relationships through conversation.
