List of lingua francas
Nepali is the lingua franca of the many ethnic, religious and cultural communities of Nepal, and is also spoken in Bhutan, parts of India and parts of Myanmar (Burma). It is one of 23 official languages of India incorporated in 8th annex of the Indian Constitution. It has official language status in the formerly independent state of Sikkim and in West Bengal's Darjeeling district. Similarly, it is spoken by the Nepalese living in the state of Assam and other Northeast Indian states. While Nepali is closely related to the Hindi–Urdu complex and is mutually intelligible to a degree, it has more Sanskritic derivations and fewer Persian or English loan words. Nepali is commonly written in the Devanagari script, as are Hindi, Sanskrit and Marathi.
