vaikuttuvat

Vaikuttuvat is a Finnish verb form. It is the present passive plural of vaikuttaa, the verb meaning to influence or affect. In this form, the subject of the sentence is the entity that is influenced, while the agent performing the influence is typically not stated. Passive constructions often omit the agent, leaving the affected entity and the influence itself as the focus.

Vaikuttuvat is used in neutral, formal language across journalism, science, and policy discourse. It describes how external factors, events, or other entities change the state or outcomes of the subject. The agent can be expressed with a genitive phrase (for example, “asukkaiden mielipiteistä” = “by residents’ opinions”) or left implicit.

Examples:

Päätökset vaikuttuvat asukkaiden mielipiteistä. (The decisions are influenced by residents’ opinions.)

Tulokset vaikuttuvat mittausvirheistä. (The results are affected by measurement errors.)

Note: The singular passive form is vaikuttuu (it is influenced); the plural form vaikuttuvat is used for multiple subjects. In contrast, the active form vaikuttaa corresponds to “influences” or “affects.”
