Morphemic structure of russian and belarusian adjective color names: general and specific

The article is devoted to the comparative study of the modern Russian and Belarusian languages at the morphemic level. It is proved that it is the contrastive study that makes it possible to reveal the features of the morphemic organization of the equivalent lexical units of the Russian and Belarusian languages, to clearly see the real degree of lexical coincidence and mismatch of closely related languages using the example of morphemic word structures. The article gives a classification of interlingual Russian and Belarusian adjective color correlates depending on the nature of their morphemic structure. The coincidence of both the structures themselves as a whole and individual morphemes, as well as their specific differences, which indicates the national specificity of each of the compared closely related languages. The conclusion is made about the importance of this type of research in solving an urgent problem in Russian linguistics – establishing the similarity and difference between two closely related languages at the morphemic level, which will contribute to a deeper understanding of the ways of development of the word-formation systems of the Belarusian and Russian languages, the features of their correlation and interaction in the conditions of state bilingualism.
