Old Bulgarian, also known as Old Church Slavonic, is the earliest attested Slavic language. It served as the liturgical language for many Slavic Orthodox churches. Think of it as the 'OG' Slavic language! π Saints Cyril and Methodius standardized it to translate religious texts. It's not spoken today but crucial for understanding Slavic linguistic history. It's like studying Latin to understand Romance languages. Its influence is evident in modern Slavic languages.
