Title: Zmiany funkcji znaczeniowych północnosłowiańskiego datiwu
Abstract: The article focuses on the analysis of the North Slavic dative in its semantic (“specific” in the concepcion of Kuryłowicz and Heinz) functions. The examples are chosen from a few texts such as Old Russian Повесть временных лет or Old Polish Rozmyślanie przemyskie, Kodeks Działyńskich and other. I am exploring the meanings of dative from a traditional point of view, referring to such types as dativus commodi/incommodi, dativus possessivus, dativus finalis, dativus ethicus. The main aim of the article is to look at the phenomenon of the North Slavic dative from a diachronic perspective.
