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.
Bosnian language
The Bosnian language (; "bosanski" / босански ) is the standardized variety of Serbo-Croatian mainly used by Bosniaks. Bosnian is one of three such varieties considered official languages of Bosnia and Herzegovina, along with Croatian and Serbian, and also an officially recognized minority or regional language in Serbia, Montenegro, and the Republic of Kosovo.
