Perustelluista

Perustelluista is a Finnish word that translates to "justified," "grounded," or "well-founded" in English. It is used as the plural partitive case of the adjective "perusteltu." This form indicates that something is plural and is being discussed in a way that emphasizes its component parts or a portion of a group.

In practice, "perustelluista" would be used in sentences where the subject being discussed consists of multiple items, arguments, or reasons that are themselves justified or well-supported. For example, one might discuss "perustelluista syistä" which means "for justified reasons." This implies that a decision or action has been taken based on multiple, sound explanations.

The word derives from "perusta," meaning "base" or "foundation." The suffix "-eltu" indicates a past passive participle, suggesting something has been given a foundation or basis. Therefore, "perusteltu" literally means "having been given a foundation." The "perustelluista" form extends this to a plural context, referring to multiple entities that possess this quality of being well-founded. It is a common term in legal, academic, and formal discussions where the need for clear and logical reasoning is paramount.
