he article presents the results of research on the idea of «conceptosphere» in modern science. The main emphasis is placed on the semantic spheres represented by the meanings of words in the language. The authors conclude how much is the culture of a nation, its folklore, literature, science, fine art, historical experience, and religion is rich, so the concept sphere of the people is richer. In addition, the concept sphere of a person is a field of knowledge made up of concepts as its units. There are reflected the sources of the conceptual unit of ideas from which the world view of the language speaker is formed. The article analyzes the main trends of concepts that form the concept sphere, which enter into correlating relationships, hierarchies with other concepts by their individual characteristics.The specific nature of the system relations of concepts requires research, but the General principle of systematicity undoubtedly applies to the national conceptual sphere, as thinking itself presupposes the categorization of thought objects, and categorization presupposes the ordering of its objects.The article summarizes the conceptual system, which should be considered in terms of mental representations, mental lexicon, and the language of thought that are part of it. The term «cognitive space» also defines an individual cognitive space – a structured set of knowledge and ideas that has any lingual person, every speaker. In their work, the authors highlight the collective cognitive space, represented by a structured set of knowledge and ideas that must be possessed by all individuals belonging to a particul ar society. Attention is paid to the distinction between the concept sphere and the semantic space of the language. According to the authors’opinions, the concept sphere presupposes the existence of a mental sphere. The mental sphere consists of concepts that exist in the form of concepts, diagrams, gestalts, mental pictures, frames, scenarios. The semantic space of a language is that part of the concept sphere that is expressed by means of language signs. The semantic space of language is the subject of co gnitive linguistics research due to the fact that most of the conceptosphere of the human ethnos is represented within the semantic space of language.
