Middle Indo-Aryan languages
The Middle Indo-Aryan languages (or Middle Indic languages, sometimes conflated with the Prakrits, which are a stage of Middle Indic) are a historical group of languages of the Indo-Aryan family. They are the descendants of Old Indo-Aryan (OIA; attested through Vedic Sanskrit) and the predecessors of the modern Indo-Aryan languages, such as Hindustani (Hindi-Urdu), Bengali and Punjabi.
