geyser (n.)

1780, extended from Icelandic Geysir, name of a specific hot spring in the valley of Haukadal, literally "the gusher," from Old Norse geysa "to gush," from Proto-Germanic *gausjan, suffixed form of PIE *gheus-, extended form of the root *gheu- "to pour." Taken by foreign writers as the generic name for spouting hot springs, for which the native Icelandic words are hverr "a cauldron," laug "a hot bath."
