An Etymological Dictionary of the German Language/Annotated/Morast

by Friedrich Kluge

Morast, masculine, ‘morass,’ Modern High German only from Low German moras; compare Dutch moras, moeras, English morass, Middle English mareis. The cognates, as is indicated by the non-Teutonic accent, are borrowed from Romance; compare Italian marese, French marais, Middle Latin maragium, ‘morass, swamp.’ The o of the Teutonic words is due to their being connected with Moor. Unknown to Suabian and Bavarian.
