Hindi (Devanagari: हिन्दी, IAST: Hindī), or Modern Standard Hindi (Devanagari: मानक हिन्दी, IAST: Mānak Hindī) is a standardised and Sanskritised register of the Hindustani language. In India, the official standardized variety of the language is based primarily on the Khariboli dialect of Delhi and other nearby areas of northern India. Hindi, written in the Devanagari script, is one of the official languages of the Government of India, along with the English language. It is one of the 22 scheduled languages of the Republic of India. Contrary to the popular belief, Hindi is not the national language of India because no language was given such a status in the Indian constitution.
