context: The Cyrillic script /sɪˈrɪlɪk/ is a writing system used for various alphabets across Eurasia, particularly in Eastern Europe, the Caucasus, Central Asia, and North Asia. It is based on the Early Cyrillic alphabet developed during the 9th century AD at the Preslav Literary School in the First Bulgarian Empire.[4][5][6] It is the basis of alphabets used in various languages, especially those of Orthodox Slavic origin, and non-Slavic languages influenced by Russian. As of 2011, around 250 million people in Eurasia use it as the official alphabet for their national languages, with Russia accounting for about half of them.[7] With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the European Union, following Latin and Greek.[8]
