aktiivisiin

Aktiivisiin is the illative plural form of the Finnish adjective aktiivinen, meaning active. In Finnish, adjectives agree with the nouns they modify in number and case, and the illative plural suffix for adjectives is -isiin. Therefore, aktiivisiin is used to describe multiple subjects that are active when the sentence conveys movement toward, participation in, or engagement with those subjects.

Typical usage and function

-Aktiivisiin modifies a plural noun in illative case, as in phrases like aktiivisiin ryhmiin or aktiivisiin työntekijöihin, where the meaning is “to the active groups” or “to the active employees.”

-The illative expresses direction into or involvement with the referenced group or concept, and the adjective form mirrors this by taking -isiin to match the plural illative context.

-Common contexts include participation, joining, engagement, or movement toward a group characterized as active.

Examples

- Osallistuin aktiivisiin ryhmiin. (I participated in the active groups.)

- He pyrkivät liittymään aktiivisiin projektiryhmiin. (They aimed to join the active project teams.)

Notes

- Aktiivisiin is one member of a broader system where adjectives decline to match case and number; other illative plural adjectives follow the same pattern (for example vihreisiin, kauniisiin).

- The form helps distinguish not only number but also the directional or participatory nuance of a statement.
