Diwa is the Tagalog word for "spirit," "soul," or "essence" — related to diwata (fairy). Used as a unisex Filipino name.
Diwa is rare but distinctive.
Diwa 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 Diwa reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
