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.
Urdu
Apart from specialized vocabulary, spoken Urdu is mutually intelligible with Standard Hindi, another recognized register of Hindustani. The Urdu variant of Hindustani received recognition and patronage under British rule when the British replaced the local official languages with English and Hindustani written in Nastaʿlīq script, as the official language in North and Northwestern India. Religious, social, and political factors pushed for a distinction between Urdu and Hindi in India, leading to the Hindi–Urdu controversy.
