By David Edenden : Good article on the Slavic languages of the former Yugoslavia. (Could include Bulgaria, I guess).Balkan Baby:
"What language do we speak when we are in the countries that once made up Yugoslavia? In Slovenia and Macedonia the answer is quite simple since these two countries both had their own languages which were recognized by the Yugoslav Government. For Bosnia, Croatia, Montenegro and Serbia the answer is maybe not quite so clear. Some people will say Serbo-Croat, whilst others will instead answer with Serbian or Croatian and more recently Bosnian and Montenegrin. Is there a right answer to this this question?"
