Violette is the French form of Violet — from the Latin viola, the small purple spring flower symbolizing modesty in the language of flowers.
Violette is widely used in France. Violette Leduc (1907-1972) was the French writer of La Bâtarde.
Violette 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 Violette reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
