Vuk Stefanović Karadžić was a Serbian philologist, anthropologist and linguist. He was one of the most important reformers of the modern Serbian language. For his collection and preservation of Serbian folktales, Encyclopædia Britannica labelled Karadžić "the father of Serbian folk-literature scholarship." He was also the author of the first Serbian dictionary in the new reformed language. In addition, he translated the New Testament into the reformed form of the Serbian spelling and language.

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.
