Here are Jain baby girl names starting with S, with simple meanings rooted in Jain values and Sanskrit heritage:

• Shanti — peace, calmness; reflects inner tranquility and non-violence.
• Shreya — auspicious, fortunate; goodness and well-being.
• Sumedha — wise, having a good mind; sound judgment and wisdom.
• Siddhi — spiritual attainments, perfection; auspicious outcomes.
• Shobha — radiance, beauty, splendor; luminous virtue.
• Sadhvi — a virtuous, renounced her; a seeker on the Jain path (note: typically used for women who have become or are in the spirit of renunciation).
• Sveti/Shveti — white, pure; purity of conduct and mind (often used in Jain contexts as a name element).
• Suvarna — golden; precious and valuable, symbolizing divine worth.
• Shital — cool, serene; calm and self-controlled nature.
• Sarika — a melodic, graceful name (often used in Jain communities as a gentle, virtuous girl’s name).
• Sakhi — companion, friend; evokes loyalty and supportive companionship.
• Sanvi — a calm and wise person; often chosen for its soft, gentle sound.

A few notes:

• Sadhvi is a title/role in Jain practice (renunciate) but is sometimes used as a name in modern contexts; ensure it fits your family tradition.
• Many of these names are shared across Jain and broader Indian naming traditions, but the meanings above align with Jain values like non-violence, wisdom, renunciation, and virtue.
• If you’d like, I can tailor a list to a preferred Jain sect (Digambara or Śvetāmbara) or suggest Sanskrit spellings that align with your family’s pronunciation.

If you want more options or names with specific meanings (e.g., tied to particular virtues like Ahimsa, Dana, or Tap) I can expand the list.
