Parvati (पार्वती) means "daughter of the mountains" in Sanskrit — from parvata (mountain). She is the Hindu goddess of love, fertility, and devotion — consort of Shiva, mother of Ganesha and Kartikeya.
Parvati is among the most important goddesses in Hindu tradition — her many forms include Durga and Kali.
Parvati 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 Parvati reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
