racjonalnej

Racjonalnej is the feminine singular form of the Polish adjective racjonalny, used to describe feminine nouns and to express the genitive, dative, or locative case in Polish grammar. It does not function as a standalone noun or concept; rather, it serves as a grammatical ending that indicates meanings such as “of a rational,” “to/for a rational,” or “about a rational” in phrases like racjonalnej decyzji, racjonalnej strategii, or o racjonalnej decyzji.

The base adjective racjonalny derives from Latin rationalis, via historical development in Polish. The semantic core is related to reason, logic, and sound judgment. The feminine form racjonalnej preserves this meaning while agreeing with feminine singular nouns in the specified cases.

In usage, racjonalnej commonly occurs with feminine nouns such as decyzja (decision), strategia (strategy), argumentacja (argumentation), czy krytyka (critique). Examples include racjonalnej decyzji (genitive), dla racjonalnej decyzji (dative), o racjonalnej decyzji (locative), racjonalnej argumentacji (genitive). These constructions appear frequently in academic writing, policy discussions, and everyday speech where rational justification or evaluation is discussed.

Related terms include racjonalność (rationality) as a noun form and racjonalnie (rationally) as an adverb, which share the same semantic field. The use of racjonalnej complements the broader concept of rationality in Polish, allowing precise grammatical agreement with feminine nouns across cases. Overall, racjonalnej functions as a case-specific inflection rather than a separate lexical entry.
