Iravati is from the Sanskrit इरावती (Irāvatī — river, abounding in waters). Iravati is one of the Sanskrit feminine names — central to traditional Hindu Vedic heritage.
Iravati 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 Iravati reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
