Magadhi Prakrit
Magadhi Prakrit was a Middle Indic language spoken in present-day Bihar, and eastern Uttar Pradesh. Its use later expanded southeast to include some regions of modern-day Bengal, Odisha, and Assam, and it was used in some Prakrit dramas to represent vernacular dialogue. Preserved examples of Magadhi Prakrit are from several centuries after the theorized lifetime of the Buddha, and include inscriptions attributed to Asoka Maurya.
