Anaelle (אנאל) combines the Hebrew ana (he has answered) and el (God) — "God has answered." A modern Hebrew-French feminine name particularly popular in France.
Anaëlle Drouet is the French Olympic épée fencer.
Anaelle 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 Anaelle reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
