THE PROBLEM OF PRESERVING MOTHER TONGUE BY ETHNODISPERSAL GROUPS (EXEMPLIFIED BY SLAVIC DIASPORAS OF TOMSK REGION)
The problem of native language preservation of Slavic diasporas in Tomsk region is considered. The factors determining the process of saving / loss the native language are revealed. The study showed that the Slavic diasporas have significantly lost their native languages in the first decades after resettlement to Siberia during the ethno-cultural adaptation. National languages support was provided by mononational settlements, national schools, religious life, influx of new migrants. Consequently, the absence of these factors narrowed the scope of communication in mother tongue greatly, which gradually led to its significant loss. Among the most studied diasporas the Poles shows the lowest level of natural language knowledge. In modern times the expected interest in learning mother tongue in etnodispersal groups is not observed.
