What is the origin of hindi language?
Hindi evolved from Prakrit which itself evolved from the devnagri script which in turn owes it’s origins to sanskrit. 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.[9] (These local dialects are still spoken, each by large populations.) In the span of nearly a thousand years of political subjugation to Muslim rulers (the Delhi Sultanate and the Mughal Empire) using Persian as their official language, Khari Boli adopted many Persian and Arabic words. As for the ultimately Arabic words, since almost every one of them came via Persian, their form in Hindi-Urdu does not preserve the original phonology of Arabic. Hindi is the most widely spoken of India’s national languages. It is spoken mainly in northern states of Rajasthan, Delhi, Haryana, Uttarakhand, Uttar Pradesh, Madhya Pradesh, Chattisgarh, Himachal Pradesh, Jharkhand and Bihar, and is spoken alongside regional language
