Gentagelig

Gentagelig is a Danish adjective meaning capable of being repeated or performed again. The term is formed from the verb gentage (to repeat) combined with the suffix -lig, indicating a characteristic. In everyday Danish it is used to describe actions, tests, or results that can be repeated under similar circumstances.

In scientific and technical usage, gentagelighed (the corresponding noun) is commonly used to refer to the concept of repeatability: the degree to which a result can be obtained again when the same procedure is carried out under the same conditions, typically in a short time frame and with the same equipment and operator. The term is often encountered in metrology, quality control, and experiments as a way to express consistency of measurements or processes.

Gentagelighed is sometimes discussed alongside related concepts such as reproducibility (reproducerbarhed). In Danish terminology, gentagelighed or gentagelighedens kvalitet is typically linked to repeatability—minor variations due to random effects within a controlled setup—whereas reproducibility concerns variation when conditions are changed, such as different instruments, operators, or locations.

Common examples include manufacturing tolerances, where a part is said to have high gentagelighed if successive productions yield dimensions within the specified tolerance under the same process settings, or laboratory measurements, where repeated assays produce consistent results. Practical assessment of gentagelighed involves statistical measures of dispersion and controls for systematic bias.
