Vyazhyz

Classification and Dialects
Vyazhyz (Вѣжызгі Vjaezhyzgi) is an extinct descendant of Old Church Slavonic. Spoken from around 1090 to the present in Southern Bulgaria, the language features six cases and six verb forms. The name likely comes from Old Church Slavonic вѣштати meaning "to speak". Its regular grammar keeps any notable dialects from forming. The language is especially similar to its parent language in its lexicon, though in later speech Greek played a larger role in shaping vocabulary due to literary influence.
