Languages with official status in India
Even though the English language is not included in the Eighth Schedule (as it is a foreign language), it is one of the official languages of the Union of India.
Of the 22 official languages, 15 are Indic, four are Dravidian, two are Tibeto-Burman, and one is Munda.
Hindi
Hindi is the "lingua franca" of the "Hindi belt", and to a lesser extent other parts of India (usually in a simplified or pidginized variety such as Bazaar Hindustani or Haflong Hindi). Outside India, several other languages are recognized officially as "Hindi" but do not refer to the Standard Hindi language described here and instead descend from other dialects of Hindustani, such as Awadhi and Bhojpuri. Such languages include "Fiji Hindi", which is official in Fiji, and Caribbean Hindustani, which is a recognized language in Trinidad and Tobago, Guyana, and Suriname. Apart from specialized vocabulary, spoken Hindi is mutually intelligible with Urdu, another recognized register of Hindustani.
