All the languages enumerated so far belong to the Indo-Aryan family. Apart from a few other minority Indo-Aryan languages, like Buksa Tharu and Rana Tharu (of Udham Singh Nagar district in the south-east), Mahasu Pahari (found in Uttarkashi in the north-west), and Doteli, Uttarakhand is also home to a number of indigenous Sino-Tibetan languages, most of which are spoken in the north of the state. These include Jad (spoken in Uttarkashi district in the north-west), Rongpo (of Chamoli district), and several languages of Pithoragarh district in the north-east: Byangsi, Chaudangsi, Darmiya, Raji and Rawat. Another indigenous Sino-Tibetan language, Rangas, became extinct by the middle of the 20th century. Additionally, two non-native Sino-Tibetan languages are also represented: Kulung (otherwise native to Nepal) and Tibetan.
