Ferdinand de Saussure is widely considered to be the founder of both modern linguistics and structuralism. The first to establish the structural study of language, he identified the difference between the system of language (‘Langue’) and the idiosyncratic speech of individuals (`Parole`), and was first to distinguish between the ‘synchronic’ study of language (language at a given time), and the ‘diachronic’ (language as it changes through time). This Companion brings together a team of leading scholars to offer a fresh new account of Saussure`s work. As well as looking at his pioneering and renowned Course in General Linguistics of 1916, they consider his lesser-known early work, his more recently-discovered manuscripts, and his influence on a range of other disciplines, such as cultural studies, philosophy, literature and semiotics. With contributions by specialists in each field, this comprehensive and accessible guide creates a unique picture of the lasting importance of Saussure’s thought.
