Proto-Karto-Zan
Proto-Georgian–Zan language
Reconstructed ancestor of the Karto-Zan languages
Proto-Georgian–Zan (also referred to as Proto-Karto-Zan) is a reconstructed language which is the common ancestor of Karto-Zan languages.[1] It is hypothesized to have diverged from Proto-Kartvelian during the 19th century BC[2] and to have split into the ancestor of the Zan languages and the Georgic languages (ancestor of Judaeo-Georgian and Georgian and dialects) around the 8th century BC or 7th century BC.[3]
