Überprüfbar

Überprüfbar is a German adjective meaning able to be checked, tested, or verified. It derives from the verb überprüfen (to check, verify) plus the suffix -bar, which marks capability. The term is used for statements, hypotheses, data, and evidence that can be confirmed or falsified through observation, experimentation, or analysis. An überprüfbare Behauptung is a claim that is supported by accessible methods and results; a claim that cannot be tested is not überprüfbar.

In grammar, überprüfbar behaves like other -bar adjectives. It is used attributively or predicatively: eine überprüfbare Hypothese, das überprüfbare Ergebnis, die überprüfbaren Daten. The negation is nicht überprüfbar. The related synonyms prüfen (to test), verifizierbar (verifiable), and prüfbar describe degrees or aspects of testability.

In scientific and journalistic contexts, verifiability is valued: Aussagen should be überprüfbar, meaning there exist procedures or evidence to confirm them. The term is sometimes discussed alongside Falsifizierbarkeit (falsifiability) in the philosophy of science. Falsifizierbarkeit concerns whether a claim can be tested so that it could be shown false; verifizierbarkeit concerns whether it can be verified by evidence. Thus, überprüfbar emphasizes testability and evidentiary support rather than ultimate truth.
