Anah (עֲנָה) means "answer" or "reply" in Hebrew. In Genesis 36:24, Anah was the discoverer of the hot springs in the wilderness while pasturing his father Zibeon's donkeys — one of the few biblical women credited with a discovery.
Mother (or father) of Aholibamah, Esau's Hivite wife.
Anah 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 Anah reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
