Karelian language
In contrast to other languages and dialects, the Tver Karelian language continues in its archaic form. Most probably, it is close to a Karelian proto-language. Vocabulary of Tver dialect was influenced by and borrowed from the language of the medieval Egonskoy villages (which no longer exist). Reliable information about the origin of writing of the Tver Karelian language is not available. By 1930, Karelian was commonly written in Cyrillic and or the Latin script.
