Dialects of Serbo-Croatian
Kajkavian is spoken in North Croatia, including the capital Zagreb, as well as in a few enclaves in Austria, Hungary, and Romania. Though its speakers are ethnic Croats and Kajkavian is thus generally considered a dialect of Serbo-Croatian, it is closer to neighboring Slovene than it is to Chakavian or Shtokavian. The Kajkavian area of Croatia is bordered on the northwest by Slovene language territory. It is bordered on the east and southeast by Shtokavian dialects roughly along a line that was the former division between Civil Croatia and the Habsburg Military Frontier; in southwest along Kupa and Dobra rivers, it persisted in ancient (medieval) contact with Chakavian dialects.
Bartol Kašić
Kašić called the language used in "Ritual rimski" as "naški" ("our language") or "bosanski" ("Bosnian"). He used the term "Bosnian" even though he was born in a Chakavian region: instead he decided to adopt a "common language" ("lingua communis"), a version of Shtokavian Ikavian, spoken by the majority the speakers of Serbo-Croatian. He used the terms "dubrovački" (from Dubrovnik) for the Ijekavian version used in his Bible, and "dalmatinski" (Dalmatian) for the Chakavian version.In Croatian:
