The author proposes an information on the semiological approach to language starting from the systemic perspective (later to be said structuralist) which has been introduced by the Saussure. A group of notions can be delineated, which are distributed in binomial oppositions: language and verb, synchronia and diachronia, meaning and signified (which define the linguistic sign, which arbitrary character is being discussed) and other oppositions. The descriptive study of linguistic units of the chain concerns phonetics and phonology. The regulations for constructing a coherent message concern grammar (or syntax), where the traditional, normative approach is in opposition with actual research, descriptive and structural: distributionnal grammar, transforming, categorial, functional. The application of new linguistic methods to human sciences is very promising and opens the way of an interesting meditation on human condition.
