Tausi is the Swahili word for "peacock" — borrowed from the Persian tâus. The peacock is associated with beauty and grace in East African and Persian traditions.
Tausi Likokola (born 1976) is the Tanzanian singer.
Tausi 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 Tausi reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
