Koetusta

Koetusta is a Finnish noun form that functions as the partitive singular of koetus, meaning a test, trial, examination, or experiment. The word can refer to a concrete testing event (for example in scientific, quality control, or educational contexts) or, in a broader sense, to the experience or process of being tested, subjected to a challenge, or undergoing an ordeal.

Etymology and related terms: koetus is built from the root koes- with the noun-forming suffix -tus. Related words include koe (test or example), kokeilu (experiment), koetella (to test), and koettelemus (ordeal). The form koetusta appears in grammatically appropriate contexts where the noun is used in the partitive case, for instance when referring to an indefinite amount or when the action of testing is described without a definite object.

Usage notes: In everyday Finnish, koetukset (plural) is common when speaking of multiple tests. Koetusta is used where the grammar requires the partitive or when the emphasis is on the ongoing process or partial nature of testing rather than a single definite test. The term is prevalent in technical, scientific, and educational language, as well as in literary or rhetorical writing to convey the notion of a trial or hardship.
