Montenegrin ( is an incipient standardized register of the Serbo-Croatian language as spoken by Montenegrins used as the official language of Montenegro. Standard Montenegrin 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 Bosnian.
Montenegro's language has historically and traditionally been Serbian. The idea of a Montenegrin standard language separate from Serbian appeared in 1990s and gained traction in 2000s via proponents of Montenegrin independence. Montenegrin became the official language of Montenegro with the ratification of a new constitution on 22 October 2007. The Montenegrin standard is still emerging. Its orthography was established 10 July 2009 with the addition of two letters to the alphabet, though grammar and a school curriculum are yet to be approved
