Shreyansh Kumar Jain Shastri and A. C. Woolner, the Ardhamagadhi (or simply Magadhi) Prakrit, which was used extensively to write the scriptures of Jainism, is often considered to be the definitive form of Prakrit, while others are considered variants of it. Prakrit grammarians would give the full grammar of Ardhamagadhi first, and then define the other grammars with relation to it. For this reason, courses teaching 'Prakrit' are often regarded as teaching Ardhamagadhi.[12]
