vaikuttavia

Vaikuttavia is a Finnish adjective form meaning influential or impactful. It is the partitive plural form of vaikuttava, the base meaning influenced or having influence. As a modifier, vaikuttavaa describes entities that exert influence or have a noticeable effect, and the form vaikuttavia is used when the noun it modifies is plural and in the partitive case.

The word is derived from the verb vaikuttaa, meaning to influence. Vaikuttava is formed with the present active participle suffix -va/-vä, creating adjectives from verbs. Related terms in the same semantic field include vaikuttaminen (influence or exertion) and vaikuttaja (an influencer or a person who has influence).

Usage notes: In Finnish, adjectives in predicate position after the verb olla are inflected in the partitive plural when the subject is plural; thus vaikuttavia is common in such clauses. The form is not used for definite or nominative singular nouns, where vaikuttava would appear (e.g., vaikuttava tarina). Vaikuttavia frequently appears in media, political discourse, and academic writing to describe people, organizations, ideas, or events that are considered influential or impactful.
