Nadine is the French elaboration of the Russian Nadya / Nadezhda — meaning "hope." Nadine Gordimer (1923-2014) — South African novelist and anti-apartheid activist who won the 1991 Nobel Prize in Literature "who through her magnificent epic writing has been of very great benefit to humanity". Two of her novels — Burger's Daughter (1979) and July's People (1981) — were banned by the apartheid regime; she joined the African National Congress when it was still illegal. Nadine Heredia — first First Lady of Peru.
Nadine 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 Nadine reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
