what language does Jainism speak

Jainism does not speak one single language.

Its scriptures and teachings are found in several languages, mainly:

• Ardhamagadhi Prakrit — very important for early Jain texts, especially Shwetambar Agamas
• Prakrit — used widely in many Jain scriptures
• Sanskrit — used in later philosophical and scholarly Jain literature
• Apabhramsha — used in some Jain works
• Regional languages — like Gujarati, Hindi, Kannada, Tamil, Marathi, and others for later Jain writings, prayers, and teachings

So, Jainism is not tied to one language; it has been expressed in many languages across time.
