Ratkaisevan

Ratkaisevan is a Finnish inflected form of the adjective ratkaiseva. It is not a standalone lexical entry; rather, it is the genitive singular form used when the noun it modifies is in the genitive. The base adjective ratkaiseva means decisive, crucial, or solution-oriented, and is derived from the verb ratkaista, meaning to solve or decide.

In Finnish, adjectives decline to agree with the nouns they modify in number and case. Therefore ratkaiseva takes various forms depending on context, such as ratkaisevan (genitive singular), ratkaisevaa (partitive singular), and ratkaiseva (nominative singular). Ratkaisevan is specifically the form you encounter when the noun is in genitive: for example, ratkaisevan suunnitelman toteuttaminen means “the implementation of the decisive plan,” and ratkaisevan roolin ottaminen means “taking on a decisive role.”

Usage and nuance: ratkaiseva describes something that has a decisive influence, outcome, or capability to resolve a matter. It is commonly used in formal or descriptive Finnish to highlight importance or effectiveness, such as decisions, plans, or roles that determine success. It can be replaced by synonyms like keskeinen or ratkaiseva in many contexts, but conveys a sense of essential impact or problem-solving capability.
