Serbian language

Serbian is the standard variety of the Serbo-Croatian language mainly used by Serbs. It is the official and national language of Serbia, one of the three official languages of Bosnia and Herzegovina, and co-official in Montenegro and Kosovo. It is a recognized minority language in Croatia, North Macedonia, Romania, Hungary, Slovakia, and the Czech Republic.

Serbian is based on the most widespread dialect of Serbo-Croatian, Shtokavian (more specifically on the dialects of Šumadija-Vojvodina and Eastern Herzegovina), which is also the basis of standard Croatian, Bosnian, and Montenegrin varieties. Reflecting this shared basis, the Declaration on the Common Language of Croats, Bosniaks, Serbs, and Montenegrins was issued in 2017. The other dialect spoken by Serbs is Torlakian in southeastern Serbia, which is transitional to Macedonian and Bulgarian.

Serbian is the only European standard language whose speakers are fully functionally digraphic (i.e., its speakers can read and write in Cyrillic and Latin alphabets interchangeably). The Serbian Cyrillic alphabet was standardized in 1814 by Serbian linguist Vuk Karadžić, who reformed it based on phonemic principles. The Latin alphabet used for Serbian was designed by the Croatian linguist Ljudevit Gaj in the 1830s based on the Czech system with a one-to-one grapheme-phoneme correlation between the Cyrillic and Latin orthographies, resulting in a parallel orthographic system.
