Adamma combines the Igbo ada (first daughter) and mma (beautiful) — "the firstborn beautiful one." A celebratory Igbo feminine name marking both birth order and praise.
Used widely among the Igbo people of Nigeria.
Adamma 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 Adamma reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
