Macrocomparativistics: new in the study of Slavic and Turkic languages

The article is devoted to the comparative analysis of the names of parts of the human head in the Slavic and Turkic languages. The relevance of its topic consists in the debatable nature of the problems of the origin of the Russian words ‘rot (mouth)’, ‘usta (mouth)’, ‘ukho (ear)’, ‘litso (face)’ and others, in the ambiguity of scientists’ opinions regarding their etymology and in the importance of solving relevant issues for the theory of linguogenetics. The purpose of the article is a comparative analysis of the nominees of human head parts in the Slavic and Turkic languages in the aspect of nostratics. In the course of the research, methods of comparison, analogy and reconstruction were used, the identity of the origin of the names of the ear, mouth, face and some other parts of the head in the Slavic and Turkic languages was established, and the position that the formal-sound and semantic differences of the compared words do not go beyond the general laws of language divergence was substantiated. The results of the work can be useful for the theory of comparative historical linguistics and for the practice of compiling etymological dictionaries of the languages of Eurasia.
