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.
Languages of the European Union
Due to the close similarity between Croatian, Serbian, Bosnian, and Montenegrinwhich are mutually intelligibleit was proposed that only one hybrid language be accepted as an official EU language as opposed to four separate ones (as in the International Criminal Tribunal for the former Yugoslavia) in order to reduce translation costs. In negotiations with Croatia, however, it was accepted that Croatian would become a separate official EU language.
