vorgeführt

Vorgeführt is the past participle of the German verb vorführen, meaning to demonstrate, present, or show something to an audience. It is used when something is displayed or explained in a live or planned demonstration, rather than simply described. In everyday language, a typical sentence is: Der Forscher hat den neuen Prototyp vorgeführt. In this construction the auxiliary verb haben governs the tense: er hat vorgeführt, er hatte vorgeführt, etc.

Vorführen is a separable-prefix verb. In main clauses, the prefix often appears separated: Er führte den Prototyp vor. In the perfect tense the participle is vorgeführt: Er hat den Prototyp vorgeführt. In passive constructions one can also say Es wird vorgeführt. As an attributive participle, vorgeführt can modify a noun: eine vorgeführte Demonstration, der vorgeführte Prototyp.

Vorgeführt is used primarily in contexts of demonstrations, technology, science, media, marketing, and public events. It can carry the nuance of a deliberate, staged presentation intended to illustrate functionality, operation, or performance more clearly than a verbal description alone.

Etymology and related terms: vorführen comes from vor- (in front, before) and führen (to lead, guide). Related verbs include demonstrieren (to demonstrate) and vorzeigen (to show or present something, often a document or item). The noun form for the act is Vorführung, meaning a demonstration or presentation.
