Perustuvan

Perustuvan is a Finnish linguistic term referring to the present active participle form of the verb perustua, which means to be based on or to rest on. In Finnish, present participles formed with the suffix -va/-vä function as adjectives and can modify nouns to express basis, foundation, or origin. The form perustuvan is the inflected version used when the participle is declined for case and number, for example in contexts where it accompanies a noun in genitive or in attributive phrases.

In practical use, perustuva describes something that is founded on a particular basis, evidence, or data. It can be attached to nouns to indicate that the described item rests on a specified foundation, such as a theory, data set, or methodological premise. Common collocations include phrases like perustuvan mukaan and perustuvan perusteella, conveying meanings such as “according to the basis” or “on the basis of this.”

Etymology and morphology: perustuvan derives from the root perusta, meaning foundation, together with the present-participle suffix -va/-vä and the inflectional ending -n. This construction is part of Finnish participial and adjective formation, allowing the expression of a modifier that states the source or justification for a claim or conclusion.
