auslösender

Auslösender is the attributive participle form of the German verb auslösen, meaning "triggering" or "initiating." In German, it is used as an adjective to describe a noun that causes a process, reaction, or event.

It is used across fields such as psychology, medicine, biology, and engineering to specify the agent or factor that starts something: for example, ein auslösender Reiz (a triggering stimulus), ein auslösender Faktor (a triggering factor), or eine auslösende Ursache (a triggering cause).

Grammatically, auslösender is an attributive adjective and declines like other weak or mixed declension adjectives, depending on the gender and case of the noun it modifies and on whether the article is definite or indefinite. Examples: der auslösende Reiz (masculine nominative), die auslösende Reaktion (feminine nominative), das auslösende Ereignis (neuter nominative), die auslösenden Reize (plural).

Distinctions: auslösen is the verb; ausgelöst is the past participle meaning "triggered" as in "eine ausgelöste Reaktion." Auslöser is the noun for the trigger or initiator; auslösend is less common as a noun but used in compounds or in certain contexts.

In practice you might see phrases such as "Der auslösende Reiz wurde identifiziert" in clinical notes or reports to denote the triggering stimulus that initiated a reaction.
