rozumnej

Rozumnej is the feminine singular genitive and dative form of the Polish adjective rozumna, which means reasonable or sensible. It appears when the adjective modifies a feminine noun in the genitive or dative case, and it can also occur in fixed phrases such as z rozumnej strony (“from a reasonable standpoint”).

In practice, rozumna is the base form used in the nominative singular (rozumna kobieta — a reasonable woman). When declined, the form changes to rozumnej in cases like genitive singular (rozumnej odpowiedzi — of a reasonable answer) or dative singular (do rozumnej decyzji — to a reasonable decision). The stem rozum- comes from rozum, meaning mind or reason, and the suffix -na marks the feminine adjective.

Nuance and usage: rozumna emphasizes rationality and thoughtfulness, akin to “reasonable” or “sensible.” It is somewhat more neutral or descriptive than synonyms like sensowna (sensible, practical) or rozsądna (wise, prudent). In everyday language, rozumna is common, while rozumnej appears primarily in grammatically inflected phrases involving feminine nouns. It can describe people, decisions, or things attributed with reasonableness, for example: nie rozumnej odpowiedzi (not a reasonable answer), do rozumnej decyzji (to a reasonable decision), z rozumnej strony (from a reasonable standpoint).
