Sushma is from the Sanskrit suṣmā (सुष्मा — most beautiful). Sushma Swaraj (Sushma Sharma, 1952-2019) was an Indian politician and Supreme Court advocate — widely considered one of the women leaders in modern Indian politics. Held nine Cabinet portfolios across her career. Padma Vibhushan (2020, posthumous, India's second-highest civilian honor). Outstanding Parliamentarian Award (2004). Member of the Bharatiya Janata Party (BJP).
Sushma 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 Sushma reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
