Karto-Zan languages
The Karto-Zan, also known as Georgian-Zan, languages are a branch of Kartvelian language family that contains Georgian and Zan languages. Svan language forms the other branch of the Kartvelian family, showing characteristic differences from Karto-Zan group. It has been hypothesized that divergence between Svan and Proto-Kartvelian language goes back as far as 19th century BCE. Georgian and Zan languages on the other hand diversified from Proto-Georgian-Zan language during 7th century BCE. Both languages share common archaic words related to metallurgy and agriculture absent in Svan.Classification
