Aporna (অপর্ণা) is a Bengali and Sanskrit name meaning "complete" or "leafless" — an epithet of the goddess Parvati, who performed austerities so severe she stopped eating even leaves.
Aparna Sen (born 1945), the Bengali filmmaker, is the most internationally known bearer.
Aporna 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 Aporna reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
