Manini is from the Sanskrit māninī (proud, dignified, self-respecting). 4th century CE) by Kalidasa — widely considered one of the greatest classical Sanskrit poets; the concept of māninī (feminine dignity) is central to Sanskrit aesthetic and ethical philosophy. Manini Chadha (born 1965) — Indian academic. Manini De Almeida — Brazilian-American figure. Manini Mishra — Indian-American academic. Princess Manini — modern Indian royal heritage naming. The Indian-American population (over 4.6 million in the US) has continued to preserve Sanskrit heritage naming through cultural centers, temples, and Hindu educational organizations across the United States.
Manini 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.
