Here are some Jain-friendly girl names starting with “Nit” along with simple meanings:

1. Niti – धर्म, सदाचरण; right conduct, morality
2. Nitika – नीति वाली, सदाचारिणी; one who follows righteous principles
3. Nitimā / Nitima – बहुत नैतिक, धर्मपरायण; highly ethical, virtuous
4. Nityā – नित्य, शाश्वत; eternal (reminds of the soul’s eternal nature)
5. Nityashrī / Nityashree – नित्य + श्री; eternal auspiciousness, ever-blessed
6. Nityanshī / Nityanshi – नित्य का अंश; part of the eternal (soul)
7. Nityābhā / Nityabha – नित्य प्रकाश; eternal light, inner spiritual radiance

All these names are rooted in Sanskrit-style meanings like dharma, niti, nitya, which fit very well with Jain values such as right conduct (सम्यक् चारित्र) and the eternal nature of the soul (आत्मा नित्य है).
