Perustuvaksi

Perustuvaksi is a Finnish grammatical form derived from the verb "perustua," which translates to "to be based on," "to be founded on," or "to rely on." Specifically, "perustuvaksi" is the translative case of the third infinitive of the verb "perustua." This form is used to indicate a change or transformation into a state of being based on something.

The translative case in Finnish often expresses the idea of "becoming" or "turning into." When applied to the third infinitive of "perustua," it signifies the process or result of something becoming established or founded upon a particular basis or reason. For example, a sentence might describe a theory "perustuvaksi" becoming accepted, meaning it is transforming into an accepted theory due to its underlying evidence or reasoning.

This grammatical construction is less common in everyday spoken Finnish and is more frequently encountered in formal writing, academic texts, or legal documents where precise descriptions of causality or foundation are required. It highlights the conceptual shift from simply existing to existing as something based on a specific foundation. Understanding "perustuvaksi" requires grasping both the meaning of "perustua" and the function of the translative case in Finnish grammar.
