verificabile

Verificabile is an Italian adjective meaning capable of being verified or proven true through observation, measurement, or evidence. It is formed from the verb verificare and the suffix -abile, which denotes ability or capacity. In ordinary use, a claim, result, or document described as verificabile can be checked against data or observable criteria.

In philosophy and the philosophy of science, verifiability (verificabilità) is a criterion used to assess the meaningfulness of statements. A verifiable proposition is one for which there exists a possible observation or experiment that could confirm it. The concept is closely associated with logical positivism and the verification principle, which emphasizes empirical testability and observational confirmation as markers of meaningful discourse.

In scientific practice, verifiability concerns the ability to reproduce and confirm findings. A verifiable experiment yields results that can be independently checked by others using the same methods, and verifiable measurements are supported by transparent procedures and data. In law, policy, and quality assurance, the term is used to indicate that claims, processes, or documents can be validated by evidence, audits, or standardized tests.

Verifiability is often discussed in relation to falsifiability, a concept popularized by Karl Popper. Popper argued that science advances through refutation rather than ultimate verification, highlighting a distinction between what can be tested to confirm and what can be disproven.

Etymology: the word derives from verificare, with the productive Italian suffix -abile, yielding a meaning of capable of verification.
