Chakavian
Chakavian in its actual use is the least spoken Serbo-Croatian dialect, being spoken only by 12% Croats. It is now mostly reduced in southwestern Croatia along the eastern Adriatic: Adriatic islands, and sporadically in the mainland coast, with rare inland enclaves up to central Croatia, and minor enclaves in Austria and Montenegro. All areas of old contacts with Romance languages.
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:
