Forms

geysa v (past tense geysta, past participle geystr), weak verb[1]

Etymology

It is inherited from Proto-Germanic *gausijaną (“to make erupt”),[2][3] the causative of the strong verb continued in gjósa (“to gush, burst out”).[4][5][6] Torp groups with them gustr (“gust of wind”), Middle Dutch guysen (“to gush out”) and Old High German gusu (“torrents”).[4] The Indo-European root is given as Proto-Indo-European *ǵʰeu- (“to pour”) in the Pokorny-based lexicons.[7]

Cleasby and Vigfússon keep it apart from geisa (“to rage”),[6] while Egilsson does not separate them in the poetry.[8]

Earliest recorded meaning

Menota's first record is AM 519 a 4to, dated 1270–1290, with the reflexive geysizk and geysask.[9] ONP's earliest dated citations, of 1275, show both the literal and the figurative use: þar geysaz vꜹtn at þeim með forsfalli “there the waters rush at them in a torrent”, and voro bøndr geystir a hendr honom “the farmers were stirred up against him”.[10]

Semantic evolution

The active verb means to set something in violent motion, as in láta geysa eld ok járn “to let fire and iron rage”, of harrying.[10][1] Most citations are of the reflexive geysask, “to rush forward”, used of crowds, the sea and floods, and of the past participle geystr “rushing, furious”, with the neuter geyst as an adverb, “violently, at full speed”.[10][6] ONP finds it most in romances, historical works and religious works.[10]

The verb continues as Icelandic geysa, Faroese goysa (“to spurt”) and Norwegian Nynorsk gøysa (“to well up”).[5][11] From it come the intensive prefix geysi- “exceedingly” and the name of the hot spring Geysir.[5][11][12]
