Nirit is from the Hebrew נִירִית (Nīrīt — Asphodelus / Asphodel wildflower). Nirit is one of the Hebrew feminine names — central to traditional Israeli heritage. Hebrew feminine name reflecting Israeli botanical heritage.
Nirit does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Nirit reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
