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".
Language secessionism
The national language of Pakistan and official languages in many parts of India, the Khariboli dialect has become the chief language variety for use in Hindi and Urdu. Grammatically, Hindi and Urdu are the same but differ in their lexicons. Hindi tends to revitalize its Sanskrit words and purges words borrowed from Persian and Arabic while Urdu does the opposite. In essence, apart from their scripts, the lexicon is what distinguishes Urdu and Hindi. Also, there are other Indo-Aryan languages that are classed as Hindi but are not necessarily the same as Hindi and Urdu. Their dialects are close to the Khariboli dialect, which sets the grammatical standard over other Indo-Aryan languages both far and near. These languages will tend to diverge, especially through the influence and accents of surrounding native languages in the communities.
