From Middle High German knobelouch, with dissimilation from klobelouch from Old High German chlobalouh (literally “clove-leek”), from Proto-West Germanic *klobulauk; from now klieben (“cleave”) and Lauch (“leek”). The dissimilated kl- was adapted to the large group of terms for thick objects beginning with kn- (cf. Knopf, Knoten, Knolle, etc.). The same in Dutch knoflook.
