Onnistuneita

Onnistuneita is a Finnish word that functions as the plural partitive form of the past participle onnistunut, meaning “having succeeded” or simply “successful.” In Finnish grammar, participles can act as adjectives, and the form onnistuneita is used when describing multiple nouns in the partitive case, typically in indefinite or partially quantified contexts.

Usage of onnistuneita occurs most often with plural nouns in the partitive case, often introduced by words like useita, monia, or useita. This construction emphasizes that the successes are not being treated as a definite, countable set. Examples include phrases such as useita onnistuneita kokeita (several successful experiments), useita onnistuneita suorituksia (several successful performances), or onnistuneita yrityksiä (successful ventures) when the noun is in partitive.

In contrast, the nominative plural form onnistuneet is used when the subject or predicate refers to the successful entities directly in a more definite sense, as in Onnistuneet kokeet ovat olleet toistuvia (The successful experiments have been repeated). The form onnistuneita therefore reflects both number and grammatical case (plural and partitive) and is a common way to describe non-specific or partially quantified successes.

Etymologically, onnistuneita comes from the verb onnistu- “to succeed,” with the past participle suffix -nut and the plural partitive ending -ta/-ta, producing the form that agrees with the object noun in number and case. Related forms include onnistunut (masculine/feminine/neuter singular), onnistuneet (nominative plural), and onnistuneita is specifically the plural partitive variant.
