oppilaitoksiin

Oppilaitoksiin is the illative plural form of oppilaitos in Finnish. The illative case expresses direction or movement into something, so oppilaitoksiin is used when talking about going to or targeting multiple educational institutions, or when actions are directed toward them. It contrasts with oppilaitokseen (into one educational institution) and oppilaitoksista (from educational institutions).

An oppilaitos is an institution that provides formal education or training. In Finland, oppilaitokset cover a wide range of types, including basic and secondary education facilities, vocational institutes and other toisen asteen oppilaitokset, universities, and universities of applied sciences, as well as adult education centers. The term is common in administrative, policy, and guidance contexts, as well as in signage or communications that indicate destinations for students and staff.

Usage examples include phrases such as "oppilaitoksiin hakeminen" (applying to educational institutions), "oppilaitoksiin liittyvät asiat" (matters related to educational institutions), and "toiminta oppilaitoksiin suuntautuu" (activity directed toward educational institutions). Grammatically, oppilaitoksiin is formed by attaching the illative plural suffix -iin to the stem oppilaitos, reflecting direction toward multiple institutions.
