Svan is a Kartvelian language spoken in the western Georgian region of Svaneti primarily by the Svan people. With its speakers variously estimated to be between 30,000 and 80,000, the UNESCO designates Svan as a "definitely endangered language". It is of particular interest because it has retained many features that have been lost in the other Kartvelian languages.

Georgian is the most widely spoken Kartvelian language; it also serves as the literary language or lingua franca for speakers of related languages. It is the official language of Georgia and the native or primary language of 87.6% of its population. Its speakers today amount to approximately 3.76 million. Georgian is written in its own unique alphabet.
