Kauravi dialect
Kauravi (Hindi: कौरवी, Urdu: کَوروی), colloquially known as Khaṛībolī or Khadiboli, is the language that is the ancestral base for the Hindustani language descended from Shauraseni Prakrit that is mainly spoken by local people in Western Uttar Pradesh, across Yamuna river (Jamna Paar) 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.
