osallistuville
Osallistuville is a Finnish grammatical form, not a standalone concept. It is the allative plural form of the participial adjective osallistuva, meaning “participating.” The allative suffix -lle marks direction or recipient, so osallistuville translates to “to the participants” or “for the participants.” It is commonly used to designate the audience, recipients, or target group of actions such as notices, programs, surveys, or services.
In practice, osallistuville appears in sentences that specify who a communication or offering is intended for.
Grammatical note: osallistuville is plural. The corresponding singular allative form would be osallistuvalle (to the participant).
