Chimamanda (Igbo Chi-ma-amanda) means "my god will never fail." Chimamanda Ngozi Adichie (born 1977) — the *Nigerian novelist whose Purple Hibiscus (2003), Half of a Yellow Sun (2006), and Americanah (2013) established her as the most internationally celebrated African novelist of her generation. Her TEDx talk We Should All Be Feminists (2012) was sampled in Beyoncé's Flawless (2013) and published as a stand-alone essay distributed to every 16-year-old in Sweden. MacArthur Fellow (2008); Women's Prize for Fiction (2007)*.
Subject of Daria de Pretis's The Adichie Method (2019).
Chimamanda 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 Chimamanda reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
