Devi (देवी) is the Sanskrit word for "goddess" — the feminine of deva (god). In Hindu tradition, Devi is the supreme goddess, the divine feminine principle, of whom Lakshmi, Saraswati, Durga, Kali, and Parvati are all manifestations.
Devi is widely used across India as both a standalone name and an honorific suffix (Lakshmi Devi, Saraswati Devi).
Devi 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 Devi reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
