KK: /ˈrɛzərˌvwɑr/
A large storage area for water or other fluids, often created by damming a river or stream.
The city relies on the reservoir for its drinking water supply.
**Reservoir** → It is formed from "re-" (meaning again) and "servare" (meaning to keep or save). The word "reservoir" refers to a place where water is kept or saved again for future use.
Think of a place that 'keeps' ('servare') water 'again' ('re-') — that's why a reservoir is a storage for water.
