Etymology

The city's name is first mentioned by Xenophon in his expeditionary logs in Achaemenid Assyria of 401 BC, during the reign of the Persian Achaemenid Empire. There, he notes a small Assyrian town of "Mépsila" (Ancient Greek: Μέψιλα) on the Tigris around where Mosul is today (Anabasis, III.iv.10). It may be safer to identify Xenophon's Mépsila with the site of Iski Mosul, or "Old Mosul," about 30 km (19 mi) north of modern Mosul, where six centuries after Xenophon's report, the Sasanian Empire 's center of Budh-Ardhashir was built. In any case, "Mepsila" is doubtless the root of the current name.

In its current Arabic form and spelling, the term Mosul, or rather "Mawsil," means "linking point"—or, loosely, "Junction City," in Arabic. On Mosul's eastern side are the ruins of the ancient city of Nineveh, and Assyrians still call the entire city Nineveh (or Ninweh).

Mosul is also nicknamed al-Faiha ("the Paradise"), al-Khaḍrah ("the Green"), and al-Hadbah ("the Humped"). It is sometimes called "The Pearl of the North" and "the city of a million soldiers."
