Serbian Cyrillic alphabet
The Serbian Cyrillic alphabet is a variation of the Cyrillic script used to write the Serbian language, updated in 1818 by the Serbian philologist and linguist Vuk Karadžić. It is one of the two alphabets used to write modern standard Serbian, the other being Gaj's Latin alphabet.
