Bosnian language

Bosnian is a standardized register of the Serbo-Croatian language, a South Slavic language, used by Bosniaks. Bosnian is one of the three official languages of Bosnia and Herzegovina, along with Croatian and Serbian.
Standard Bosnian is based on the most widespread dialect of Serbo-Croatian, Shtokavian, more specifically on Eastern Herzegovinian, which is also the basis of Standard Croatian, Serbian, and Montenegrin. Until the dissolution of SFR Yugoslavia, they were treated as a unitary Serbo-Croatian language, and that term is still used in English to subsume the common base (vocabulary, grammar and syntax) of what are today officially four national standards, although the term is no longer used by native speakers.
