Learn one of the most important languages in the world: Hindi
Hindi (हिन्दी, Hindustani pronunciation: [ˈhɪndi]), or more precisely Modern Standard Hindi (मानक हिन्दी), is a standardised and Sanskritised register of the Hindustani language. Modern Standard Hindi is one of the official languages of India.
As of 2009, the best figure Ethnologue could find for speakers of actual Hindustani Hindi was 180 million in 1991. In the 2001 Indian census, 258 million (258,000,000) people in India reported Hindi to be their native language. However, this number included millions of people who were native speakers of related languages but who thought of their speech as a dialect of Hindi.
