perusteiden

Perusteiden is a Finnish term built from peruste, meaning basis, foundation, reason, or justification. The form perusteiden is the genitive plural, used to express “of the bases” or “the bases’ grounds.” In both everyday and formal Finnish, perusteet refer to the underlying justification for a claim, decision, or policy, and the concept is common in legal, administrative, and academic writing. For example, phrases like päätöksen perusteet denote the grounds for the decision.

In law and administration, perusteet denote the reasons or evidence supporting a conclusion. They are often used in expressions such as valituksen perusteet (grounds for appeal) or päätöksen perusteet (the basis for the decision). Clearly stated perusteet help ensure transparency and accountability by showing how conclusions were reached and what arguments or data they rest upon.

In education, the term appears in phrases like opetussuunnitelman perusteet or perusopetuksen perusteet, referring to the official curriculum guidelines or core principles governing a level of education. The concept also appears in philosophical or argumentative writing when outlining the perusteet for a claim or proposal. Overall, perusteiden denotes the foundational grounds that justify actions, rules, or positions in Finnish discourse.
