An Etymological Dictionary of the German Language/Annotated/Strauch

Strauch, masculine, ‘shrub, bush,’ from the equivalent Middle High German strûch, masculine (to which the Modern High German collective Gesträuck is allied); wanting in Old High German. Corresponding to Dutch struik, ‘shrub’ (also Dutch stronk, ‘shrub,’ equivalent to Low German Strunk, with a nasalised root syllable). The stem is not found in other languages; the relation of the cognates of Modern High German straucheln is dubious.
