Аннотация:This article deals with research on the usage of the literary Czech language in the written tradition outside the Czech ethnic territory. The author devotes attention to aspects of language hybridization as a basis for the emergence of local varieties of some literary languages. The aim of the article is to point out the less commonly examined side of the history of literary Czech and to verify the legitimacy of contact linguistics as a point of departure for the investigation of this history outside the Czech lands.
