Hanan (حنان) is the Arabic word for "compassion" or "tenderness" — particularly the warm, affectionate feeling of a mother.
Hanan Ashrawi (born 1946), the Palestinian scholar and politician, is the most internationally known bearer.
Hanan 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 Hanan reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
