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.
Slovenia
A significant number of people in Slovenia speak a variant of Serbo-Croatian (Serbian, Croatian, Bosnian, or Montenegrin) as their native language. These are mostly immigrants who moved to Slovenia from other former Yugoslav republics from the 1960s to the late 1980s, and their descendants. In 2002, 0.4% of the Slovenian population declared themselves to be native speakers of Albanian and 0.2% native speakers of Macedonian. Czech, the fourth-largest minority language in Slovenia prior to World War II (after German, Hungarian, and Serbo-Croatian), is now the native language of a few hundred residents of Slovenia.
