Languages with official status in India
The Constitution of India designates the official language of the Government of India as Hindi written in the Devanagari script, as well as English. There is no national language as declared by the Constitution of India. Hindi is used for official purposes such as parliamentary proceedings, judiciary, communications between the Central Government and a State Government. States within India have the liberty and powers to specify their own official language(s) through legislation and therefore there are 22 officially recognized languages in India of which Hindi is the most used. The number of native Hindi speakers is about 25% of the total Indian population; however, including dialects of Hindi termed as Hindi languages, the total is around 44% of Indians, mostly accounted from the states falling under the Hindi belt. Other Indian languages are each spoken by around 10% or less of the population.
Linguistic history of India
The establishment of British rule in the subcontinent saw the clear division of Hindi and Urdu registers. This period also saw the rise of modern Hindi literature starting with Bharatendu Harishchandra. This period also shows further Sanskritization of the Hindi language in literature. Hindi is right now the official language in nine states of India— Uttar Pradesh, Bihar, Rajasthan, Jharkhand, Madhya Pradesh, Chhattisgarh, Uttarakhand, Haryana and Himachal Pradesh—and the National Capital Territory of Delhi. Post-independence Hindi became the official language of the Central Government of India along with English. Urdu has been the national and official language of Pakistan as well as the lingua franca of the country.
