Maeva is the Tahitian word for "welcome" — adopted as a French feminine name, particularly popular in the late 20th century.
Used widely in France and French Polynesia.
Maeva 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 Maeva reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
