About the etymology of specific manuscript old-Russian oikonyms of the XIV-XVII centuries with the stems of the Baltic origin

In the article etymologies of some Old Russian place-names with stems of the Baltic origin, mentioned in chronicles in 14th-17th centuries, are considered. By the side of names, Baltic sources of which stems are more or less clear (Veveresk, Vory, Gerten, Demen, Isterva, Istya, Kornike (Korniki), Kushel), there are toponyms that may be explained from both Baltic and Slavonic languages with the equal degree of reliability (Bolki. Degunino, Kunei, Obolchi). Their double etymologies are due to both the genetic relationship between these groups of languages and their close interaction in the toponymical system of the area these names are located in: the North-West of Russia, the basin of Oka and Upper Volga. They are derived from stems belonging to various lexical groups: apellatives, hydronyms, anthroponyms. In the structural aspect place-names present lexico-semantic, morphological and grammatical procedures of toponymical word-formation.
