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.
Vlachs in the history of Croatia
Socioculturally, there were two main ethnic divisions in the Croatian Military Frontier, those of the "native" "Croats" and "immigrant" "Vlachs". The Croats were Catholics, Habsburg subjects, made up of an agrarian population concentrated around frontier towns, of nuclear families, and linguistically predominantly Chakavian-speaking (or Chakavian-based speech). The Vlachs were holders of patriarchal-pastoral culture of the Dinaric, refugees from Ottoman and Venetian territories, of extended families, and linguistically Neo-Shtokavian-speaking.
