What is the name of city aberdeen?

The name "Aberdeen" is derived from two Gaelic words:

Aber, meaning "mouth of a river"

Deen, either referring to the name of the River Dee or to the Celtic god Devena.

Thus, Aberdeen is believed to mean "mouth of the River Dee" or "Devena's mouth." The settlement's name was recorded as "Aberdon" in 1179 and "Aberden" in 1319.
