This document provides an overview of structuralism and the ideas of Ferdinand de Saussure. It defines structuralism as studying the basic units and rules that make up any system. For language, the units are words and the rules are grammar. Saussure viewed language as a system of signs, where each sign is a combination of a signifier (sound image) and signified (concept). He also distinguished between langue (the system) and parole (individual usage), and discussed syntagmatic (linear) and associative relations between linguistic units.
