Standard Serbian is based on the most widespread dialect of Serbo-Croatian, Shtokavian (more specifically on Šumadija-Vojvodina and Eastern Herzegovinian dialects), which is also the basis of Standard Croatian, Bosnian, and Montenegrin. 

Serbian is practically the only European standard language whose speakers are fully functionally digraphic, using both Cyrillic and Latin alphabets. 

The Serbian Cyrillic alphabet was devised in 1814 by Serbian linguist Vuk Karadžić, who created the alphabet on phonemic principles.
