1. A naturally occurring underground hollow or passage, especially one with an opening to the surface of the Earth. Caves can form through a variety of processes, including the dissolution of limestone by flowing water, the differential cooling of volcanic magma (which occurs when the outside surface of the lava cools, but the inside continues to flow downwards, forming a hollow tube), or the action of wind and waves along a rocky coast.

Etymology

Origin of cave

1175–1225; Middle English < Old French < Late Latin cava (feminine singular), Latin cava, neuter plural of cavum hole, noun use of neuter of cavus hollow

Explanation

A cave is hollow space underground that's big enough for a person to walk or crawl into. People who explore caves often wear battery-powered headlamps. You might see a small cave in the side of a cliff as you hike up a mountain, or swim into an underwater cave when you go snorkeling. In either case, a cave is a deep, carved-out chamber that opens above ground — or in the water. People who regularly explore caves are called spelunkers, or cavers. The Latin root word is cavea, "hollow."
