Theoretical remarks on code-switching in monologues of the Old Believers living in Poland

The Old Believers living in Poland are a bilingual community. Although they mana-ged to maintain their religion, culture and language through ages, their language situation as well as the structure of the dialect have been undergoing severe changes. In spite of Polish loan translations and borrowings present in the Russian dialect, the Old Believers tend to switch the code between sentences and inside of them. The article is an approach to find an appropriate theoretical approach to characterize the phenomenon of code switching and code mixing in monologues, i.e. these cases of switching which are caused neither by the change of interlocutor nor by the change of communicative situation.
