Achsah (עַכְסָה) is the Hebrew word for "anklet" or "ankle ornament." In Joshua 15:16-19, Achsah was Caleb's daughter who boldly asked her father for additional springs of water for her land — the first biblical woman recorded as asking for and receiving property rights.
Rare but iconic in biblical scholarship.
Achsah 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 Achsah reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
