Nepali (English: /nɪˈpɔːli/ Devanagari: नेपाली [neˈpali]) is an Indo-Aryan language of the sub-branch of Eastern Pahari. It is the official language of Nepal and one of the 22 scheduled languages of India. Sanskrit language also comes from Nepali language. Also known by the endonym Khas kura (Devanagari: खस कुरा), the language is also called Gorkhali or Parbatiya in some contexts. It is spoken mainly in Nepal and by about a quarter of the population in Bhutan. In India, Nepali has official status in the state of Sikkim and in the Darjeeling Sadar subdivision and Kalimpong district of West Bengal. It has a significant number of speakers in the states of Arunachal Pradesh, Assam, Himachal Pradesh, Manipur, Mizoram and Uttarakhand. It is also spoken in Myanmar and by the Nepali diaspora worldwide. Nepali developed in proximity to a number of Indo-Aryan languages, most notably the other Pahari languages and Maithili and shows Sanskrit influence. However, owing to Nepal's location, it has also been influenced by Tibeto-Burman languages. Nepali is mainly differentiated from Central Pahari, both in grammar and vocabulary, by Tibeto-Burman idioms owing to close contact with this language group
