Here are some common Jain terms that start with M, with brief, authentic meanings:

• Mahavira: The 24th Tirthankar, a supreme teacher in Jainism whose life and teachings form a central part of Jain dharma.
• Mahavrata: The great vows taken by ascetics (monks and nuns) — non-violence, truth, non-stealing, celibacy, and non-possession.
• Moksha: Liberation from the cycle of birth and death; ultimate spiritual goal.
• Mukti: Release or liberation; another way to say Moksha.
• Moha: Delusion or illusion; one of the root causes of bondage in Jain psychology.
• Muni: A Jain monk (a male ascetic); one who has renounced worldly life and follows strict vows.
• Matha: A Jain religious center or monastery; place for study, worship, and discipline.
• Mithyā-darśana (sometimes used as “mithyā” related terms): Wrong/false perception; opposite of samyak-darśana (proper right perception).

If you’d like, I can expand any of these with how Digambar and Śvetāmbar traditions explain them, or add more terms starting with M.
