Claudine is the French feminine diminutive of Claude — from the Latin claudus (lame). Claudine Longet (born 1942) — French-American singer.
Claudine 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 Claudine reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
