Kauravi dialect

Kauravī or Kauravi (Hindi: कौरवी, Urdu: کَوروی, Hindustani pronunciation: [kɔːɾ.ʋiː]), colloquially known as Khaṛībōlī or Khadiboli (Hindustani pronunciation: [kʰə.ɽiː boː.liː]), is a dialect and ancestral base for the Hindustani language descended from Shauraseni Prakrit that is mainly spoken by local people in Western Uttar Pradesh, across Yamuna river (Jamnapaar) in Delhi and Haryana, at the bordering areas with Uttar Pradesh and in Uttarakhand plains. Modern Hindi and Urdu are two standard registers of Hindustani, descending from Old Hindi, originally called Hindavi and Dehlavi which gained prestige when it was accepted along with Persian as a language of the courts. Before that, it was only a language the Persianate states (like Delhi Sultanate) spoke to their subjects in, and later as a sociolect of the same ruling classes. Modern Khariboli contains some features, such as gemination and pitch accent, which give it a distinctive sound and differentiates it from Braj and Awadhi. Old Hindi evolved to become the colloquial lingua franca Hindustani from which are Hindi and Urdu the respective standard registers.
