What is "ma'an"

Ma'an is a city in southern Jordan, southwest of the capital Amman. It serves as the capital of the Ma'an Governorate. Its population approximately 50,000. Civilizations with the name of Ma'an have existed at least since the Nabatean period—the modern city is just northwest of the ancient town. The city is an important transport hub situated on the ancient King's Highway and also on the modern Desert Highway.
