The Swiss linguist Ferdinand de Saussure (1857-1913) has exerted a profound influence not only on twentieth century linguistics but on a whole range of disciplines within the humanities and social sciences. His central thesis was that the primary object in studying a language is the state of that language at a particular time–a so-called synchronic study. He went on to claim that a language state is a socially constituted system of signs that are quite arbitrary and that can only be defined in terms of their relationship within the system.H01
