Roman Jacobson , one of the thinkers of the Prague School, spoke about the bilateral nature of language and argued that every linguistic sign is organized in two modes of organization: attachment and choice.
Ferdinand de Saussure, from the point of view of language as a system of representation and marking, created the basic binary opposition world-language, and saw each word as containing the pair of concepts - 'signifier' (the arbitrary word chosen to represent something in the world), and 'marked' - the object or The concept of them she symbolizes. Other binary concepts de Saussure coined in the context of the linguistic system are synchronous-diachronic, langue-parole. In general, within the framework of the structuralist conception, the linguistic system is composed of pairs of opposites (day / night, good / bad, etc.), and each concept can be understood only against the background of its difference from its opposite. Subsequently, the structure of binary opposition was applied and used to explain human and social phenomena in different fields of knowledge.
