çekim: karşılaştırma düsterer · üstünlük am düstersten
köken: From Middle Low German dûster, from Old Saxon thiustri, ultimately from Proto-West Germanic *þiustrī (“dark, without light”). The word also exists in parts of West Central German (compare Luxembourgish däischter), which probably facilitated the borrowing; but the standardised form is definitely from Low German in view of its lacking diphthongisation.
köken: Inherited from Middle French morne, from Old French morne, murne, (compare Old French morner (“to mourn”)), from Frankish *murn, from Proto-Germanic *murnaz. Cognate with English mourn, Old Norse morna (“to pine away”), Gothic 𐌼𐌰𐌿𐍂𐌽𐌰𐌽 (maurnan).
