"Slavonic" refers to a group of languages and dialects spoken by the Slavic peoples, primarily in Eastern Europe and parts of Central Europe. These languages are part of the larger Indo-European language family and include major branches such as West Slavic, East Slavic, and South Slavic. Examples of Slavonic languages include Polish, Russian, Czech, and Bulgarian. Historically, the term "Slavonic" also relates to the Old Church Slavonic, the first literary Slavic language, developed in the 9th century by the Saints Cyril and Methodius. This language played a crucial role in the spread of Christianity among the Slavic peoples and laid the foundation for many modern Slavonic languages.
