Here are simple Jain-friendly boy names starting with “Ku,” along with their meanings where they fit Jain context:

• Kushal — skilled, clever; often used in Jain and broader Indian contexts.
• Kushagra — sharp-minded, intelligent.
• Kunal — lotus; a name with calm, virtuous connotations in many traditions including Jain.
• Kunal — noble, virtuous; gentle and balanced.
• Kyuśh (often written as Kush) — short form of Kushal/Kushagra; carries the same positive sense.
• Kusumendra — lord of flowers; sometimes used in Jain communities with a floral/metaphysical feel.
• Kuber (Kubera) — king of wealth; in Jain texts it’s used reverentially as a seasonal or symbolic name (be mindful of associations with the Hindu deity; many Jain families use it respectfully as a name).
• Kumud — lotus blossom; serene and pure imagery.
• Kumar — prince; common, traditional name used across many Indian communities, including Jain.

If you’d like, tell me any preferences (e.g., meaning you want, length, traditional vs. modern, starting with a different syllable after Ku), and I’ll tailor a shorter list.
