Like many other modern Indian languages, it is believed that Hindi had been evolved from Sanskrit, by way of the Middle Indo-Aryan Prakrit languages and Apabhramsha of the Middle Ages. Though there is no consensus for a specific time, Hindi originated as local dialects such as Braj, Awadhi and finally Khari Boli after the turn of tenth century.[13] In the span of nearly a thousand years of Muslim influence, such as when Muslim rulers controlled much of northern India during the Delhi Sultanate and the Mughal Empire, many Persian and Arabic words were absorbed into khari boli and was called Urdu or Hindustani. Since almost all Arabic words came via Persian, they do not preserve the original phonology of Arabic.
