Putu is from the Balinese Putu — first-born child. Putu is one of the Balinese unisex names — central to traditional Balinese Hindu Indigenous heritage. The Balinese birth-order naming heritage is one of the caste-neutral Indigenous naming systems in the world.
Putu 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 Putu reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
