proef

Proef is a Dutch noun with several related meanings centered on testing, sampling, or demonstration. The primary sense is a test or trial of something’s quality, capacity, or performance. It can also refer to an attempt or effort to determine how something works or to achieve a result. In addition, proef denotes a sample or tasting, such as a small portion of food or a preview of a product.

In science and research, a proef refers to an experiment or test run. Common compounds include proefopstelling (experimental setup) and proefpersoon (a test subject or participant). In education, proefwerk is a term for a school test or exam, and the idea of making an initial attempt is captured in phrases like “een proef doen.” In everyday language, proef can describe any trial or attempt, for example an early or tentative try.

In gastronomy and product testing, proef is used for tastings or sample evaluations, such as wine or beer proef and proeverij (tasting event). In publishing and printing, proefdruk denotes a proof copy used to check text and layout before mass printing; the term is also encountered in contexts where a final version is reviewed.

Other related Dutch terms include proefperiode, meaning a probationary period, and proefrit, a test drive. Across its uses, proef remains a versatile word signaling examination, sampling, or demonstration, often appearing in compound words to specify the type of test or sampling involved.
