Here are some Jain-friendly boys’ names starting with C, along with simple meanings:

• Chetan — conscious, living; full of life
• Charan — feet; a metaphor for humility and service
• Chaitanya — consciousness, spirit, intellect
• Chandrakant — beloved of the moon; poetic and gentle
• Chandraprabha — moonlight; (note: often used as a feminine name in common usage, but some families use Chandraprabha for boys as well)
• Chirag — lamp, light; illumination

If you’d like, tell me any sounds you prefer (e.g., soft vs. strong, traditional vs. modern) and I can tailor a shorter, more specific list.
