The official language is Serbian, native to 88% of the population. Serbian is the only European language with active digraphia, using both Cyrillic and Latin alphabets. Serbian Cyrillic is designated in the Constitution as the "official script" and was devised in 1814 by Serbian philologist Vuk Karadžić, who based it on phonemic principles. A survey from 2014 showed that 47% of Serbians favour the Latin alphabet, 36% favour the Cyrillic one and 17% have no preference.
