perustelemalla
Perustelemalla is a Finnish verb that translates to "by justifying," "by giving reasons," or "by arguing." It is the instructive form of the verb "perustella," which means to justify, to give reasons for, or to argue for something. The "-lla" ending in Finnish is a case ending that indicates a means or instrument, similar to how "by" or "with" might be used in English. Therefore, "perustelemalla" signifies the act of performing an action or achieving a state through the process of providing justification or reasoning.
In practice, "perustelemalla" implies that an action is not arbitrary but is supported by a logical explanation
