Taraji is from the Swahili taraji ("hope, expectation"). Taraji P. Person of Interest (2011-2013), Acrimony (2018).
Taraji 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 Taraji reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
