IPA: /ˈbækˌwɔːtə/
KK: /ˈbækˌwɔtər/
A body of water that is not part of the main flow, often stagnant or isolated. It can also refer to a place or situation that is considered backward or not progressive.
The small town was a backwater, far removed from the bustling city life.
Backwater → It is formed from "back" (from Old English *bæc*, meaning the rear or reverse side) and "water" (from Old English *wæter*, meaning water). The term "backwater" refers to a body of water that is stagnant or not flowing, often found at the back or in a remote area.
Think of the 'rear' ('back') of a river where the water is 'stagnant' ('water') — that's why backwater refers to a quiet, still area of water.
