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.
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.
