racionalne

Racionalne is the feminine plural form of the adjective racionalan in several South Slavic languages, including Croatian, Bosnian, Serbian and Slovenian. It means “rational” or “based on reason” and is used to describe feminine plural nouns. For example, racionalne odluke means rational decisions and racionalne ideje means rational ideas.

Grammatically, racionalne agrees with feminine plural nouns in the nominative and accusative cases. In these languages, adjectives must match the gender, number and case of the nouns they modify, and racionalne is the standard feminine plural form. In Slovenian you will encounter phrases such as racionalne odločitve (rational decisions), reflecting the same agreement pattern.

Etymology and usage: the form derives from the Latin rationalis, through the historical development of European languages into Slavic tongues. The term is widely used in philosophy, science and everyday language to describe methods, arguments or outcomes that are reasoned, logical or evidence-based. While the basic meaning remains constant, its exact collocation can vary by language, with different synonyms or stylistic nuances in Croatian, Serbian, Bosnian and Slovenian.
