Among Syrians and neighbouring regions, Ad-Deir is used for short to indicate Deir ez Zor. The current name, which has been extended to the surrounding region, indicates an ancient site for one of the Early Christian secluded monasteries spread since the persecution times and Apostolic Age throughout Mesopotamia. Although Deir, which is Arabic for "monastery", thought to be kept throughout Medieval and Modern Age renaming, Zor, which indicates the riverbank bush, appeared only in some late Ottoman records.
