Kajkavian
The major cities in northern Croatia are located in what was historically a Kajkavian-speaking area, mainly Zagreb, Koprivnica, Krapina, Križevci, Varaždin, Čakovec. The typical archaic Kajkavian is today spoken mainly in Hrvatsko Zagorje hills and Međimurje plain, and in adjacent areas of northwestern Croatia where immigrants and the Štokavian standard had much less influence. The most peculiar Kajkavian dialect "(Baegnunski)" is spoken in Bednja in northernmost Croatia. Many of northern Croatian urban areas today are partly Štokavianized due to the influence of the standard language and immigration of Štokavian speakers.
Languages of the European Union
Due to the close similarity between Croatian, Serbian, Bosnian, and Montenegrinwhich are mutually intelligibleit was proposed that only one hybrid language be accepted as an official EU language as opposed to four separate ones (as in the International Criminal Tribunal for the former Yugoslavia) in order to reduce translation costs. In negotiations with Croatia, however, it was accepted that Croatian would become a separate official EU language.
