Kouluilla

Kouluilla is a Finnish word form that represents the plural adessive case of koulu, meaning "at the schools" or "in the schools." It is used to indicate location when referring to more than one school and to describe where actions occur or where something exists.

Formation and use: The plural noun for schools is koulut. Attaching the adessive suffix -lla to the plural stem yields kouluilla, the form used when stating something about multiple schools. The adessive case typically answers questions like where, at which place, or during what setting. In contrast, other cases such as inessive (kouluissa) or illative (kouluun) express slightly different spatial nuances, such as “in the schools” or “into the schools.”

Examples: "Kouluilla on monipuolisia tiloja, kuten kirjasto ja liikuntasali." This sentence states that at the schools there are various facilities. "Kouluilla järjestetään yleisötapahtumia." Here, events are organized at the schools. In contrast, phrases like "kouluissa" would mean “in the schools,” emphasizing the interior space rather than the location of activities.

Context: Kouluilla appears frequently in educational reporting, policy discussions, and descriptions of regional education infrastructure. It functions as a common locative expression when the reference includes multiple institutions rather than a single school.
