Sätestanud

Sätestanud is an Estonian word functioning as the past active participle of the verb sätestama. In Estonian grammar, past active participles describe actions that were completed before the moment of reference and behave similarly to adjectives, agreeing with the noun they modify in number and case. The form sätestanud is built from the verb stem sätest- and the participle suffix -anud, yielding a meaning of “having tested” or “having tried.”

Usage of sätestanud is relatively rare in everyday speech. In modern Estonian, speakers more commonly use katsetanud or proovinud to express the sense of “having tested” or “having tried.” Sätestanud may appear in formal, literary, or technical writings, and in historical texts where the sense of a tested or assessed method, item, or result is needed.

Morphologically, sätestanud behaves like an adjective in a sentence. It can modify a noun and agree with it in number and case, for example in phrases like sätestanud meetod (the method that has been tested) or meetod, mis on sätestanud, depending on the syntactic construction. When used in predicates with auxiliary verbs, it participates in compound tenses similarly to other past participles.

Overall, sätestanud represents a specific grammatical form in Estonian used to convey a completed testing action, most often found in more formal or technical contexts, with more common alternatives preferred in everyday language.
