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.
Demographics of Croatia
From 1961 to 1991, the official language was formally designated as Serbo-Croatian or Croato-Serbian. Even during socialist rule, Croats often referred to their language as Croato-Serbian (instead of Serbo-Croatian) or as Croatian. Croatian and Serbian variants of the language were not officially recognised as separate at the time, but referred to as the west and east version, and had different alphabets: the Latin alphabet and Serbian Cyrillic. Croatians are protective of their language from foreign influences, as the language was under constant change and threats imposed by previous rulers (i.e. Austrian German, Hungarian, Italian and Turkish words were changed and altered to "Slavic" looking/sounding ones).
