A layer of rock or soil underground that can hold and transmit water, often used as a source of drinking water.
The town relies on the aquifer for its water supply.
Aquifer → It is formed from "aqua" (from Latin, meaning water) and "fer" (from Latin "ferre", meaning to bear or carry). An aquifer is a geological formation that bears or carries water, allowing it to be stored and transmitted underground.
Think of 'water' ('aqua') being 'carried' ('fer') underground — that's what an aquifer does.
