KK: /ˈwɔːtərˌkuːlər/
A machine that cools and dispenses drinking water, often found in offices or public places.
The office installed a new watercooler to provide fresh water for the employees.
Watercooler → The word is formed from "water" (from Old English *wæter*, meaning liquid that falls as rain or is found in rivers) and "cooler" (from the verb "cool" meaning to lower the temperature, combined with the suffix "-er" indicating a device or agent). A watercooler is a device that cools water for drinking.
Think of 'water' as the liquid we drink and 'cooler' as a device that lowers its temperature — together, they describe a device that provides cool drinking water.
