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.
Croats
Besides Shtokavian, Croats from the Adriatic coastline speak the Chakavian dialect, while Croats from the continental northwestern part of Croatia speak the Kajkavian dialect. Vernacular texts in the Chakavian dialect first appeared in the 13th century, and Shtokavian texts appeared a century later. Standardization began in the period sometimes called "Baroque Slavism" in the first half of the 17th century, while some authors date it back to the end of the 15th century. The modern Neo-Shtokavian standard that appeared in the mid 18th century was the first unified Croatian literary language. Croatian is written in Gaj's Latin alphabet.
