Aarna (आर्णा) is the Sanskrit word for "flowing river" or "of the wave." Used as a modern Hindi feminine name.
Aarna is widely used in modern India.
Aarna 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 Aarna reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
