Fließendem

Fließendem is the dative singular form of the German adjective fließend. The base meaning of fließend is “flowing” or “smooth,” and it can also mean “fluent” when describing language ability. Like other German adjectives, fließend is declined to agree with the noun it accompanies, and the form fließendem occurs in the dative singular for masculine or neuter nouns when there is no article or when the context requires a strong declension.

In practice, fließendem appears in phrases such as mit fließendem Wasser or in fließendem Zustand. These examples show the strong declension pattern in which the ending -em marks the dative singular without a definite determiner. With a definite article or a determiner that signals the case, the adjective takes the weak ending fließenden (for example, dem fließenden Wasser).

Common usage notes: fließendem is primarily a descriptive adjective form related to physical flow or movement (water, rivers, streams, systems that operate smoothly). When fließend is used as an adverb to mean "fluently," it usually appears unchanged as fließend, as in er spricht fließend Deutsch; in this adverbial use, the word does not take the -em ending.

Summary: fließendem is a grammatically specific form of fließend used in the dative singular without a preceding article, e.g., mit fließendem Wasser or in fließendem Zustand, and it contrasts with the weak form fließenden in contexts with a definite determiner.
