Abstrakt:
The article is an attempt to find an adequate theoretical approach to characterize the phenomenon of code switching and code mixing in Polish-Eastern-Slavonic language contact. To analyse the situation bilingual Eastern-Slavonic groups in Poland (Russian, Belarussian and Ukrainian minorities) and Polish minority in the East (Russia, Belarus, Ukraine but also Latvia, Estonia, Lithuania and other former Soviet Republics) one needs to define the phenomena of bilingualism and code mixing (as well as code switching). It is also important to find and characterize similarities and differences between examples of code mixing described in P. Auer’s, P. Muysken’s, R. Franceschini’s and other authors’ works on one side, and in Polish-Eastern-Slavonic bilingualism on the other.
