Onnistunut

Onnistunut is a Finnish adjective meaning successful or well-executed. It is the past participle form of the verb onnistua, to succeed, and is used to describe outcomes, results, or performances that have turned out favorably.

In usage, onnistunut functions as an attributive or predicative modifier and agrees with the noun it describes in number and case. Common examples include "onnistunut koe" (a successful test), "onnistunut hanke" (a successful project), and "onnistuneita kokeita" (successful experiments, plural). The corresponding forms follow Finnish inflection patterns for adjectives, such as "onnistuneen kokeen" (genitive singular) and "onnistuneet hankkeet" (nominative plural).

Etymologically, the word derives from the verb onnistua and shares the semantic field of positive outcome. It is often used in everyday language, journalism, and evaluation contexts to indicate that an action, plan, or event has met its objectives.

Nuances and related terms: onnistunut emphasizes the outcome itself, whereas related adjectives like menestyksekäs highlight broader success or reputation. The noun form is onnistuminen (the act or state of succeeding), and the adverbial form is onnistuneesti (successfully).
