vaikuttavan

Vaikuttavan is the genitive singular form of the Finnish adjective vaikuttava, meaning influential or impactful. The term derives from the verb vaikuttaa, “to influence” or “to affect.” Vaikuttava as a base form is used to describe someone or something that possesses influence, while vaikuttavan appears when the adjective modifies a noun in the genitive case.

In Finnish, adjectives agree with the noun in case and number, so vaikuttavan is used before a genitive noun. Examples: "vaikuttavan henkilön tarina" (the story of the influential person) or "vaikuttavan päätöksen seuraukset" (the consequences of the influential decision). The same base adjective takes other inflectional forms in different contexts, for instance the nominative form is vaikuttava and the partitive form is vaikuttavaa, depending on sentence structure and syntax.

The term is common in journalism, academic writing, and discourse that emphasizes power or impact. It functions as an adjective and is not a separate lexical item from vaikuttava itself. Related forms include vaikuttavuus (influence or impact as a noun) and vaikuttaja (an influencer or agent who exerts influence). These related terms help distinguish the quality of influence (vaikuttavuus) from the actor who exerts it (vaikuttaja).
