Chakavian
Chakavian or Čakavian , , ( , proper name: "čakavica" or "čakavština" , own name: "čokovski, čakavski, čekavski") is a dialect of the Serbo-Croatian language spoken by a minority of Croats. It has a low mutual intelligibility with Shtokavian. There is much internal diversity, to the point where intelligibility between the northern and southern varieties of Chakavian is low. All three main Serbo-Croatian dialects are named after their most common word for "what?", which in Čakavian is "ča" or "ca". Chakavian is spoken mainly in the northeastern Adriatic: in Istria, Kvarner Gulf, in most Adriatic islands, and in the interior valley of Gacka, more sporadically in the Dalmatian littoral and central Croatia.
Burgenland Croatian
Smaller Croatian minorities in western Hungary, southwestern Slovakia, southern Poland and southern Czech Republic are often also called Burgenland Croats. They use the Burgenland Croatian written language and are historically and culturally closely connected to the Austrian Croats. The representatives of the Burgenland Croats estimate their total number in all three countries and emigration at around 70,000.Burgenland Croatian was the language of Croatian refugees who fled Croatia during the Turkish Wars and settled in the western part of what was then Hungary, the area where they still live. Burgenland Croats included speakers of all three dialects of the Serbo-Croatian language (Shtokavian, Chakavian and Kajkavian), with the majority being the Chakavians. They originally came from the river Una valley.
Burgenland Croats did not take part in the shaping of the present standard Croatian in the 19th century. Instead, they constructed their own written standard based mainly on the local Chakavian speech and adopted the Croatian alphabet, a modified Latin alphabet, as their script.
