Medhavi is from the Sanskrit मेधावी (Medhāvī — intelligent, wise, sharp-witted) — from Sanskrit medhā (intellect/wisdom). Medhavi is one of the Sanskrit feminine names — central to traditional Hindu Vedic heritage.
Medhavi 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 Medhavi reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
