Trübes

Trübes is the neuter singular form of the German adjective trüb, meaning turbid, cloudy or murky. It is used to describe a lack of clarity caused by suspended particles, contaminants, or other substances that reduce transparency. In everyday language it commonly refers to liquids, but it can also describe air, glass, or surfaces, as well as less tangible qualities like mood or atmosphere.

In usage, trübes is typically found with nouns such as Wasser (water), Luft (air), oder Glas (glass). With a definite article, the form becomes das trübe Wasser or das trübe Glas; with an indefinite article or without an article, the form is trübes Wasser or trübes Glas. In plural phrases the corresponding forms are trübe Gewässer (water bodies) or die trüben Gewässer when the article is specified. The term is versatile across contexts: trübes Wasser describes cloudy or opaque liquid, trübe Luft denotes hazy or polluted air, and trübe Stimmung or trübe Aussichten can convey a dreary mood or gloomy prospects.

Etymologically, trüb derives from older Germanic roots related to darkness and opacity and has cognates in related Germanic languages. The noun die Trübe exists in some contexts to denote turbidity or a somber, subdued atmosphere.
