koeteltuja

Koeteltuja is a Finnish linguistic form that corresponds to the plural partitive of the past passive participle koeteltu, meaning "tested" or "proven." It functions as an adjective or as part of a noun phrase describing items that have undergone testing.

In Finnish, participles like koeteltu are declined to agree with the noun in number and case. The suffix -ja or -uja signals a plural partitive usage, producing koeteltuja when modifying plural nouns in the partitive case, as in koeteltuja tuotteita (tested products) or koeteltuja tuloksia (tested results). The word itself does not denote a separate lexical category; its meaning is contextual, indicating that something has passed a test or verification.

Usage of koeteltuja is common in science, industry, consumer testing, quality control, and journalism. It can indicate reliability or vetted status of products, data, or statements. In everyday Finnish, the form is most often seen as part of longer noun phrases rather than standing alone.

Examples include koeteltuja tuotteita and koeteltuja tuloksia. For instance, a report might reference koeteltuja tuotteita to denote products that have undergone testing, or a study might discuss koeteltuja tuloksia as results that have been validated through procedures.
