The Khitan language is an extinct language that was spoken by the Khitan people, who established the Liao Dynasty in northern China during the 10th to 12th centuries. It is classified as a member of the Para-Mongolic languages, which are related to the Mongolic language family. The Khitan language is known primarily from inscriptions and documents, with two main scripts: the Khitan large script and the Khitan small script. Despite its historical significance, the Khitan language remains poorly understood due to the limited number of surviving texts and the complexity of its scripts. Linguists have made efforts to decipher these scripts, but many aspects of the language, including its grammar and vocabulary, are still unclear. The study of Khitan contributes to our understanding of the cultural and linguistic diversity in medieval East Asia.
