Definition

A mineral formation hanging from the ceiling of a cave, created by the gradual accumulation of mineral-rich water dripping from above. Stalactites grow downward over thousands of years and are typically composed of calcite or other minerals.

Example Usage

The cave tour guide pointed out the magnificent stalactites that sparkled under the dim lighting.

Origin

From Greek 'stalaktos' (dripping), derived from 'stalassein' (to drip).

Fun Fact

A helpful mnemonic is that stalactites have a 't' and hang from the ceiling, while stalagmites have an 'm' and rise from the ground.
