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.
