Article departs from the pre-condition of Alpine and Pannonian space that have differed already in ancient literal patterns of Slovenian language and have independently developed all the time: in Alpine space, besides Latin-German tradition, central Slovenian literal language developed and witnessed a strong dialectic differentiation after Brižinski spomeniki; in Pannonian space, besides Greek-Old Church Slavic tradition, archaic East Slovenian literal system developed that preserved an original “old Slovenian” syntax image still at the change between 18th and 19th century. The project brings new cognitions from history of Slovenian language. Two important questions shall be opened: (1) divided development of Slovenian language in Alpine and Pannonian language space and (2) question of unification of Slovenian literal norms in the middle of 19th century. In the set frame, we shall try to successfully answer both questions and show a row of new cognitions, and at the same time direct the path for further research on history of Slovenian language.
