An Etymological Dictionary of the German Language/Annotated/Frost

by Friedrich Kluge

Frost, masculine, ‘frost, cold, chill,’ from the equivalent Middle High German vrost, Old High German frost, masculine; compare Dutch vorst, Anglo-Saxon forst, English frost, Old Icelandic frost, neuter, ‘frost, cold’; a common Teutonic abstract of frieren, Gothic *friusan. Gothic *frusta-, masculine, neuter, ‘frost,’ is wanting.
