SLAVIC SUFFIXES IN THE SUBSTRATE TOPONYMY OF EASTERN OBONEZHJE
The paper deals with some of the most productive suffixes of Slavic origin used for the adaptation of geographical names of non-Russian origin to the Russian toponymic system of Eastern Obonezhje. In the toponymic system of the study area, which is the western margin of the Russian North, there is a number of substrate place names of Balto-Finnic and Saami type, which are a legacy of the ethnic groups that had once inhabited the territory. In the substrate toponymy there is a number of place names with a substrate stem and affix (es) of Russian origin (R. Vodlitsa, R. Tambitsa, I. Myandovets, B. Mutovets, Vlg. Kiprov Navolok, Vlg. Patrova, L. Artovo, L. Homino, Vlg. Korkila with one Korkinichi, etc.). A number of suffixes have been identified in the toponymy of the region, but only some of them can be combined with the foreign-language base morpheme (-itsa/-yets, -ov/-yev, -in, -ichi/-itsy). They are present in the names of objects that have a broader scope of use (names of settlements and rivers), and were subjected to Russian adaptation the earliest. The productivity of suffixes is variable due to specific functioning, spatial and chronological scope of existence of certain suffixation models.
