Forms

lösen (third-person singular present löst, past tense löste, past participle gelöst, auxiliary haben)[1]

Etymology

It is inherited from Middle High German lœsen, inherited from Old High German lōsen, inherited from Proto-West Germanic *lausijan, inherited from Proto-Germanic *lausijaną (“to make loose, set free”), derived from the adjective los “loose, free”.[2][3][1][4] The same verb is Gothic 𐌻𐌰𐌿𐍃𐌾𐌰𐌽 (lausjan), Old Norse leysa, Old English līesan, Old Frisian lēsa and Old Saxon lōsian.[4][2][5]

The adjective, Proto-Germanic *lausaz, is in turn derived from a verb meaning “to lose, loosen”, which survives in German only in the prefixed verlieren.[4][5] Köbler traces the family to Proto-Indo-European *lewH- (“to cut, separate, loosen”).[6]

Earliest recorded meaning

Old High German lōsen is recorded from the end of the 8th century in glosses and then in Tatian, Otfrid, Notker and the Muspilli; it meant “to loosen, untie”, “to free, deliver (from)”, “to ransom” and “to pay”.[6][7] The prefixed irlōsen “to redeem” and its agent noun irlōsāri “redeemer” are also of the 8th century.[2]

Semantic evolution

Middle High German lœsen meant “to loosen, free, redeem, buy back, pay”.[2] Luther uses it of freeing prisoners (der Herr löset die Gefangenen) and of redeeming a pledge or a firstborn animal, a use now taken over by einlösen and erlösen.[8][9] From redeeming something sold or pledged came “to get money by selling”, the source of Erlös (early 18th century).[8][2] The phrase eine Fahrkarte lösen “to buy a ticket” is recorded by Sanders.[8]

Other senses grew from “to make loose”: to annul a contract or engagement, to solve a riddle or a doubt, to dissolve salt in water, and formerly to fire a gun (Lessing: ich lösete das Pistol).[8][3] Hunters say of game that it löst sich, relieves itself.[10][11] The chemical sense of Lösung was shortened from Auflösung in the 19th century.[3]
