Montenegrin is a member of the South Western Slavic language family. Other languages in this language group are Macedonian, Ukrainian and Czech to name but a few.
It is spoken by Montenegrins in Montenegro where it became the official language after independence from Serbia. The orthography was established in 2009 and two additional letters were added to the alphabet at the same time.
Bosnian, Croatian, Montenegrin and Serbian are different national variants of the Serbo-Croatian language. These four languages were divided into national registers after the break-up of Yugoslavia in 1991. The languages are mutually intelligible in spoken format and also in written format if written with Latin script (Croatian uses only Latin script but Bosnian, Montenegrin and Serbian use both Latin and Cyrillic).
