Indah is the Indonesian and Malay word for "beautiful." Used widely across Indonesia as a given name and as an adjective.
Indah remains rare in the U.S.
Indah 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 Indah reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
