Jain means a follower of Jain Dharma — someone who follows the teachings of the Jinas (spiritual victors), especially the Tirthankars.

In a deeper sense, Jain refers to one who follows the path of:

• Ahimsa — non-violence
• Satya — truth
• Asteya — non-stealing
• Brahmacharya — chastity/self-control
• Aparigraha — non-possessiveness

So, the word Jain is connected with the idea of spiritual victory over inner passions like anger, ego, deceit, greed, and attachment.
