The Serbian language (српски/srpski, pronounced [srpski] in Serbian) is based on the most widespread dialect of Serbo-Croatian: Shtokavian dialect, which is also the basis of Croatian, Bosnian, and Montenegrin languages. Serbian is practically the only European standard language with complete synchronic digraphia, using both Cyrillic and Latin alphabets. Most of the Serbian words are of native Slavic lexical stock, tracing back to the Proto-Slavic language.
