An Etymological Dictionary of the German Language/Annotated/Rapunzel

by Friedrich Kluge

Rapunzel, masculine, ‘rampion, corn-salad,’ Modern High German only, not from Latin rapunculus, but rather an extended form from Middle Latin rapunciun (French raiponce, compare Dutch rapunsje), whence also Italian ramponzolo; compare further English rampion. Allied to Latin rapa (see Rübe).
