India
India is home to two major language families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by 24% of the population). Other languages spoken in India come from the Austroasiatic and Sino-Tibetan language families. India has no national language. Hindi, with the largest number of speakers, is the official language of the government. English is used extensively in business and administration and has the status of a "subsidiary official language"; it is important in education, especially as a medium of higher education. Each state and union territory has one or more official languages, and the constitution recognises in particular 22 "scheduled languages".

Hindi in Devanagari script would be the official language of the Indian Union. For fifteen years, English would also be used for all official purposes (Article 343). A language commission could be convened after five years to recommend ways to promote Hindi as the sole official language and to phase out the use of English (Article 344). Official communication between states and between states and the Union would be in the official language of the union (Article 345). English would be used for all legal purposes – in court proceedings, bills, laws, rules and other regulations (Article 348). The Union was duty bound to promote the spread and usage of Hindi (Article 351).
