"Along with the closely related Macedonian language (collectively forming the East South Slavic languages), it is a member of the Balkan sprachbund. The two languages have several characteristics that set them apart from all other Slavic languages: changes include the elimination of case declension, the development of a suffixed definite article and the lack of a verb infinitive, but it retains and has further developed the Proto-Slavic verb system. One such major development is the innovation of evidential verb forms to encode for the source of information: witnessed, inferred, or reported.
It is the official language of Bulgaria, and since 2007 has been among the official languages of the European Union.[10] It is also spoken by minorities in several other countries." - (en.wikipedia.org 21.09.2020)
