Abfließt

Abfließt is the third-person singular present tense form of the German verb abfließen. The infinitive abfließen combines the prefix ab- (away, off) with fließen (to flow), and abfließen is a separable-prefix verb. In standard present-tense usage, German writes this as two words: er fließt ab. The form abfließt may appear in some texts as a quoted or dictionary inflection, but the basic present tense is fließt ab. The verb describes the movement of liquid away from a source, typically along a surface or out of a container.

In hydrology and everyday language, abfließen refers to liquids that drain or runoff away. Examples include water that flows off a roof after rain or runoff that flows away from a paved area. The process can also be described metaphorically, such as costs, information, or time that "flow off" or diminish from a system. The noun form das Abfließen denotes the process itself, while das Abfluss refers to the physical channel or outlet through which liquid discharges.
