aufspüren

Aufspüren is a German verb meaning to locate, detect, or track down something or someone, typically through investigation, searching, or tracing. It is commonly used in law enforcement, security work, search-and-rescue missions, archaeology, and investigative journalism. The act can refer to finding a person, a clue, a hidden object, or information. The noun form das Aufspüren denotes the act of locating or tracing.

Grammatically, aufspüren is a separable verb. In present tense, the prefix is separated, as in Wir spüren das Versteck auf. In the perfect tense it uses the auxiliary haben: Wir haben das Versteck aufgespürt. The past participle is aufgespürt. The verb is transitive and typically governs a direct object, e.g., Er spürt den Täter auf; Sie spüren die Spur auf.

Synonyms and nuances include ausfindig machen, lokalisieren, aufdecken, verfolgen. Aufspüren emphasizes the active process of locating something through clues, traces, or evidence, whereas synonyms like finden are more general.

Examples:

Die Spur konnte nach Wochen endlich aufgespürt werden.

Der Suchhund spürte die vermisste Person auf.

Etymology and usage notes:

The verb combines the verb spüren (to feel or notice) with the prefix auf-, giving the sense of “discover by pursuing.” It is widely used in formal and informal contexts, particularly where systematic searching or investigative work is involved.
