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.
Comparison of standard Bosnian, Croatian, Montenegrin and Serbian
Serbian and Bosnian language standards tend to be inclusive, i.e. to accept a wider range of idioms and to use loanwords (German and Turkish), whereas the Croatian language policy is more purist and prefers neologisms to loan-words, as well as the re-use of neglected older words. Yet there is criticism of the puristic language policy even in Croatia, as exemplified by linguist Snježana Kordić. These approaches are, again, due to the different cultural, historical and political development of the three variants and the societies they are found in.
