Spül

Spül is a German term derived from the verb spülen, meaning to rinse or flush. In standard usage it is largely a bound stem rather than a freely used standalone noun, and it appears most often in compound words related to cleaning, washing, or flushing liquids.

In everyday language the full concept is usually expressed with related nouns such as Spülung (the act of rinsing or flushing), Spülwasser (rinse water), or Spülmittel (dishwashing or cleaning agent). The bare form Spül is therefore relatively uncommon outside of technical or compound contexts.

Common uses and examples of Spül-related terms include Spülwasser, the liquid used to rinse away residues; Spülgang, the rinsing cycle in dishwashers or washing machines; Spülvorrichtung, a device designed to carry out flushing or rinsing; and Spülung, which can denote a flushing or rinsing procedure in medical, dental, or industrial settings. In water supply and plumbing, terms such as Spülung der Leitungen describe flushing of pipes to remove sediments or air pockets. In medicine or biology, Spülung can refer to rinsing bodily cavities or wounds with sterile solutions, for example oralspülung (mouth rinse).

Etymologically, Spül traces to the German verb spülen, from which related forms such as Spülung, Spülwasser, and Spülmittel are derived. The term is primarily a technical or compound-building element and is not typically used as an independent noun in ordinary speech. See also Spülen, Spülmaschine, Spülbecken for related concepts.
