perusperusteeseen
Perusperusteeseen is the illative form of the Finnish noun perusperuste, meaning the basic basis or fundamental foundation. In Finnish, illative forms convey direction toward or reference to something, so perusperusteeseen is used in sentences that point to or address the basic basis in question. The term itself is not commonly used as a standalone concept in everyday language; more often, related terms such as perusperuste (singular) or perusperusteet (plural) appear, and in educational policy the standard label is perusopetuksen opetussuunnitelman perusteet.
In the context of Finnish education, perusperusteet refer to the national core curricula that guide basic education.
Related terms include perustus and peruste, which convey related ideas of basis and justification, as well
