It was the language of the common people and is categorized under Prakrit, which is a term used for a group of languages spoken in ancient India. This language was mostly spoken by the people of Magadh, a kingdom which comprised parts of Bihar
. Its popularity with the common people made it a natural choice for Lord Mahavir for preaching the Jain religion. Many of the Jain scriptures are written in this language.
