Indian literature is generally believed to be the oldest in the world. With vast cultural diversities, currently there are around two dozen officially recognized languages in India. But broadly Linguistic history of India can be classified into 3 parts:
Old Indo Aryan Languages who's earliest evidence is from Vedic Sanskrit. Then came Middle Indo Aryan Languages, Prakrits, evolved outside the learned sphere of Sanskrit. The oldest attested Prakrits are the Buddhist and Jain canonical languages Pali and Ardha Magadhi, respectively. The Indo-Aryan prakrits also gave rise to languages like Gujarati, Assamese, Bengali, Oriya, Nepali, Marathi, and Punjabi. And then came New Indo Aryan languages which presently know as Hindi and Urdu.
