Names of India in its official languages
The Republic of India has many official names expressing linguistic diversity. In most Indo-Aryan languages, the country is officially called Bhārat. Languages like Kashmiri and Urdu which were heavily influenced by Persian and Arabic continue to officially use the classical exonym Hindostān to refer the country. But the term Hindustan is also used colloquially in other languages of North India. Eventhough some Dravidian languages like Kannada and Telugu have adopted the tatsama-term Bhārataṁ as the official name of the republic, Southern-most languages like Tamil and Malayalam continue to use Indiyā to refer the country. Munda languages like Santali use the native term Siñôt to refer to the region. Tibeto-Burman languages of the northeast India-bordered regions have adopted the official name as Bhārat following the same convention as North India, although colloquially they use the term Indiyā. Hindi and English 

Although there is no national language for the country, Modern Standard Hindi (in the Devanagari script) is the official language of the Union Government of India as per Article 343 of the Constitution of India. English has the status of a "subsidiary official language" according to clause 3 of Official Languages Act, 1963. Hindi romanisation uses Hunterian transliteration, which is the "national system of romanisation in India" and the one officially used by the Government of India. Eighth Schedule languages 

The Eighth Schedule of the Indian Constitution lists 22 languages, which have been referred to as scheduled languages and given recognition, status, and official encouragement. Footnotes:
