Toponomy The name Mokotów most likely comes from the name of its former owner Mokot or Mokoto, which with addition of the suffix -ów, translates to Mokot's place. A hypothesis proposes the person's name originates from a Middle High German word mocke, meaning "clumsy" and "uneducated". Originally used for the village, now in the neighbourhood of Old Mokotów, it became a name of the city district of Mokotów. It is traditionally divided into two areas, Upper Mokotów in the west, and Lower Mokotów in the east, divided by the peaks of the Warsaw Escaprment.Kwiryna Handke: Dzieje Warszawy nazwami pisane.
