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.
Burgenland Croatian
Burgenland Croatian written language is based mainly on the local Chakavian dialect with some influences from the other Croatian dialects spoken in Burgenland. It uses the Latin alphabet with the same diacritical modifiers as the Croatian alphabet. In the course of language development it acquired some of its own specialised vocabulary, sometimes different from that used in standard Croatian.
