An Etymological Dictionary of the German Language/Annotated/seicht

by Friedrich Kluge

seicht, adjective, ‘low, shallow, flat,’ from Middle High German sîhte, adjective, ‘low, shallow’; Old High German *sîhti not recorded; probably allied to sinken, hence literally ‘where the water has sunk into the ground,’ or ‘that which has sunk, or is low’; scarcely akin to seihen, literally ‘where it gently flows’?.
