Kajkavian

Kajkavian is a South Slavic supradialect or language spoken primarily by Croats in much of Central Croatia and Gorski Kotar.

It is part of the South Slavic dialect continuum, being transitional to the supradialects of Čakavian, Štokavian and the Slovene language. There are differing opinions over whether Kajkavian is best considered a dialect of the Serbo-Croatian language or a fully-fledged language of its own, as it is only partially mutually intelligible with either Čakavian or Štokavian and bears more similarities to Slovene; it is transitional to and fully mutually intelligible with Prekmurje Slovene and the dialects in Slovenian Lower Styria's region of Prlekija in terms of phonology and vocabulary.

Outside Croatia's northernmost regions, Kajkavian is also spoken in Austrian Burgenland and a number of enclaves in Hungary along the Austrian and Croatian border and in Romania.
