The author of the article considers the metaconcepts “Caucasus” and “Asia” as the main ethno-cultural constructs of the work of the Russian-speaking writer Boris Chipchikov. The relevance of the stated topic lies in the fact that the artistic world of the bilingual author, being one of the significant fragments of the world picture, in particular the linguistic world picture, reflects the value system of the linguoculture of those ethnic groups in whose languages the works were created, in this case - the Karachay-Balkar and Russian linguocultures. The study revealed that the semantic core of the ethnic model of creativity of B. Chipchikov is composed of the metaconcepts “Caucasus” and “Asia” with a wide range of components that actualize a variety of associations that reflect the mental preferences, cognitive consciousness of the writer, his ambiguous attitude to the “native”/“to a stranger”. The work uses a number of scientific methods, including methods of conceptual, component, linguocognitive analysis (to characterize metaconcepts and concepts), the method of description (to decipher the results of the study). The results obtained can be used in the further development of the problems of bilingualism, translinguism and transculturation, which are of scientific interest to modern linguists.
