Linguistic rights
The constitution of India was first drafted on January 26, 1950. It is estimated that there are about 1500 languages in India. Article 343–345 declared that the official languages of India for communication with centre will be Hindi and English. There are 22 official languages identified by constitution. Article 345 states that "the Legislature of a state may by law adopt any one or more of the languages in use in the State or Hindi as the language or languages to be used for all or any of the official purposes of that State: Provided that, until the Legislature of the State otherwise provides by law, the English language shall continue to be used for those official purposes within the State for which it was being used immediately before the commencement of this Constitution".
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.
