równej

Równej is the feminine genitive singular form of the Polish adjective równy, which means equal, even, or uniform. The form reflects how Polish adjectives decline to agree with the gender, number, and case of the noun they modify. The base adjective równy has masculine singular forms równy, feminine singular forms równa, neuter równe, and various plural forms; równej is specifically used with feminine nouns in genitive or dative cases, and in some prepositional phrases.

In standard usage, równej appears in phrases describing feminine nouns with a sense of equality or uniformity. Common examples include o równej długości (of equal length) and o równej jakości (of equal quality). The construction typically involves a feminine noun in genitive after the preposition or in a phrase requiring a genitive form, where równej modifies that noun.

In mathematical and logical contexts, the root równ- relates to equality. The verb form means “is equal” as a predicate for masculine subjects (jest równy), while feminine subjects often use ta suma jest równa temu wynikowi (the sum is equal to this result). The abstract noun for the concept is równość, and related adjectives or phrases derive from the same root.

Etymologically, równy derives from Proto-Slavic *rovъ, reflecting a common Slavic heritage for words denoting sameness and parity. In modern Polish, równej remains a routine inflectional form used to maintain grammatical agreement in descriptive and technical language.
