Hindi-Urdu (also called Hindustani, Hindavi, and Rekhta) is the predominant language of Northern India and Pakistan. It evolved from the Kharaboli dialect spoken in Delhi, with lots of additions from Sanskrit, Arabic, Turkic and Persian. Standard Hindi is an official language of India. Standard Urdu is the official language of Pakistan and of some northern provinces in India. From a grammatical and syntactical point of view, they are nearly the same. Differences occur in vocabulary (with Urdu being more heavily influenced by other language groups and Hindi relying more on Sanskrit) and in literary tradition. Languages derived from Hindi are spoken in other countries, where it is usually called “Hindustani.” Examples are in Fiji, Surinam and Trinidad. Approximately 182,000,000 people speak Hindi as a first language; in addition there are 60,600,000 native speakers of Urdu. An estimate 120,000,000 others speak Hindi or Urdu as a second language.
