Meaza is from the Amharic ምዕዛ (Mə'eza) — fragrance, sweet scent. Meaza Ashenafi (born 1964) is an Ethiopian lawyer and judge — widely considered one of the figures of African women's law and the gender-equality movement in Ethiopia.
Meaza 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 Meaza reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
