GYE-zer/ˈɡaɪzər/

A hot spring that periodically shoots water and steam upward.

An erupting natural geyser: a forceful column of water and steam rises from a mineral-rimmed hot-spring vent, with droplets falling back into its shallow basin.
Etymology

Geysir, “the gusher,” named one particular Icelandic hot spring. Foreign writers extended its name to spouting hot springs generally, turning a place-specific name into a type of natural feature.
