From a Jain Dharma perspective:

• Arham is not a specific Jain scriptural term or title. It is commonly used as a given name in India and among various communities.
• In many cases, Arham is understood to mean “worthy” or “deserving,” derived from Sanskrit roots. Among Jains, such meanings reflect the ideal of worthiness or alignment with virtuous conduct.
• It is not a traditional or canonical Jain name tied to a particular Tirthankara or Jain text. Its use is more cultural and linguistic and can be found among Hindus and Christians as well as Muslims in different regions.
• There is no Jain prohibition on the name’s use by people of any faith, but its association with Jain ideals is indirect rather than scriptural.

If you’d like, I can share more about Jain names that explicitly reflect Jain doctrinal concepts (like names of Arihants, Siddhas, or qualities admired in Jain philosophy).
