Lavanya (लावण्य) is the Sanskrit word for "grace" or "beauty" — particularly the kind of beauty that comes from movement and grace rather than mere physical appearance.
Lavanya is widely used across India.
Lavanya 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 Lavanya reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
