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.
Dalibor Brozović
Instead of "Serbo-Croatian", Brozović preferred the term "Central South Slavic diasystem", asserting separate language status for Croatian and Serbian. However, Brozović advocated the term "Croato-Serbian" even in 1988. As far as language status is concerned, Brozović has asserted for nearly three decades that "the Serbian and Croatian variants are (...) phenomenons, which are analogous to the English and American variants"; "As in other cases where several nations use one standard language (German, Dutch, English, French, Spanish, Portuguese standard language), the standard Croato-Serbian language is not unified. In linguistics (especially in sociolinguistics), the realizations of such standard languages are called "variants of a standard language"". Brozović maintained that it is "a fact that Serbs and Croats have a common language", and he described it as pluricentric even in 1992. In the 1990s, Brozović became one of the leading proponents of linguistic purism in Croatia.
