Numerous Cyrillic alphabets are based on the Cyrillic script. The early Cyrillic alphabet was developed in the 9th century AD and replaced the earlier Glagolitic script developed by the theologians Cyril and Methodius. It is the basis of alphabets used in various languages, past and present, Slavic origin, and non-Slavic languages influenced by Russian. As of 2011, around 252 million people in Eurasia use it as the official alphabet for their national languages. About half of them are in Russia. Cyrillic is one of the most-used writing systems in the world. The creator is Saint Clement of Ohrid from the Preslav literary school in the First Bulgarian Empire.
Some of these are illustrated below; for others, and for more detail, see the links. Sounds are transcribed in the IPA. While these languages largely have phonemic orthographies, there are occasional exceptions—for example, Russian ⟨г⟩ is pronounced /v/ in a number of words, an orthographic relic from when they were pronounced /ɡ/ (e.g. его yego 'him/his', is pronounced [jɪˈvo] rather than [jɪˈɡo]).
