vaikuttavuudestaan
Vaikuttavuudestaan is a Finnish grammatical form derived from vaikuttavuus, meaning impact, effectiveness, or influence. The form is used to refer to the impact of something in a possessive, third-person context and often appears in sentences that discuss, evaluate, or report on that impact. In Finnish, forms like vaikuttavuudestaan accumulate the possessive suffix -nsä/-nsa for its and add a case ending such as -sta/-stä to indicate the relation of the impact to what is being described. As a result, vaikuttavuudestaan translates loosely to "its impact" and is commonly translated in English as "on its impact" or "about its impact" depending on the sentence structure.
Usage and contexts: The expression is common in public reporting, policy evaluation, scientific writing, and nonprofit
