The present work focuses on lexical borrowings from Russian into Middle and Lower Chulym as well as Küärik. The first part of the book is a comprehensive catalogue of currently identifiable borrowings, which have been scattered so far in various, often inaccessible, publications, and as such largely unavailable for research purposes. In the second part, the material is subjected to analysis from the point of view of phonetic and morphological adaptation and classified according to the semantic field and word class. The study concludes with an index of the Russian etyma.
