Adetokunbo is from the Yoruba Adétòkunbọ́ — adé crown + tó arrived + òkun sea + bọ́ across — the crown returned from across the seas, royalty returned from overseas. Adetokunbo is one of the Yoruba feminine + unisex names — central to traditional Nigerian + West African heritage.
Adetokunbo 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 Adetokunbo reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
