Within India, Hindi languages are spoken primarily in the Hindi belt regions and Gangetic plains, including Delhi and the surrounding areas; where they are often transitional with neighbouring lects. Many of these languages, including Braj and Awadhi, have rich literary and poetic traditions. Urdu, a Persianized derivative of Khariboli, is the official language of Pakistan and also has strong historical connections to India, where it also has been designated with official status. Hindi, a standardized and Sanskritized register of Khariboli, is the official language of the Government of India. Together with Urdu, it is the third most-spoken language in the world.
