Sania (سَنِيَّة) is from the Arabic saniyya — "brilliant, splendid, exalted" — the feminine of saniyy. Founded the Sania Mirza Tennis Academy in Hyderabad. Brand ambassador for over 30 corporate brands.
Subject of her autobiography Ace Against Odds (2016).
Sania 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 Sania reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
