The article is devoted to the linguophilosophical concept of the outstanding Russian theorist, his-torian and philosopher of language, the largest Iranian scholar Vasily Ivanovich Abaev. The as-pects of the author’s linguophilosophical concept are presented based on two works by V.I. Abaev: “Reflection of the work of consciousness in the lexico-semantic system of language” (1970) and “Language as ideology and language as technique” (1934). In these works, he pays special atten-tion to the problem of the origin of human language. The theory of the origin of language itself, in his opinion, should be based on an optimal scientific theory that proceeds from the correct theo-retical premises and is consistent with the available empirical data. To explain the origin of a lan-guage, it is not the grammar of the language that is important, but the subject–significant vocabu-lary, as he believes that the origin of vocabulary is a single and integral problem, and the origin of grammar is inevitably divided into several particular issues. Language, according to V.I.Abaev, arose not from biological, but from the social needs of a person, from the need to relate things to their collective, to impose their own “brand” on them. Special attention is paid to the concept of ideosemantics, firstly introduced by V.I. Abaev in-to scientific circulation. He distinguishes two types of semantics: small semantics (or signal, technical), which includes a mandatory minimum of semantic functions that determine the mod-ern communicative use of the word, and large semantics, which is the sum of those concomitant cognitive and emotional representations that reflect the complex inner life of the word in its past and present. He defined this broader understanding of semantics by the term “ideosemantics”. Id-eosemantics, according to V. Abaev, is the most important criterion for the historical characteriza-tion of linguistic phenomena. V. Abaev sees the value of language at an early stage of its for-mation in its “ethnodemarkation function”. In conclusion, the article presents ideosemantic parallels in three genetically and structurally diverse languages: Ossetian, Kabardino-Circassian and Karachay-Balkar.
