rationaalisista

Rationaalisista is a Finnish inflected form of the adjective rationaalinen, meaning rational. It arises in contexts where a plural noun is modified and the elative case is used, and it can translate to “from the rationalists” or “of the rationalists” depending on the sentence. It is not a standalone noun; rather, it functions as an adjective within an inflected noun phrase or as a stand‑in for a noun phrase in ellipsis.

Grammatically, rationaalisista belongs to the category of Finnish adjectives that decline for number and case. The elative plural suffix -ista/-istä attaches to the stem, producing rationaalisista when the governing noun is plural. The exact meaning is determined by the noun it modifies and by the broader clause.

Usage notes and examples: In academic or descriptive writing, you might encounter phrases such as rationaalisista ihmisistä puhuttiin, meaning “There was discussion about the rationalists” or “about the rational people.” Another example is rationaalisista argumenteista esitettiin vastaväitteitä, meaning “Objections were raised to the rational arguments.” The form is most common when referring to a group described by rational thinking and is typically paired with a compatible plural noun.
