Parzystej

Parzystej is the feminine singular inflected form of the Polish adjective parzysty, meaning “even” in the sense of parity or divisibility by two. It is used with feminine nouns and appears in the genitive, dative, and locative singular. The same adjective takes different endings in other cases and with other genders, but parzystej specifically signals feminine agreement in those cases.

In mathematics and everyday Polish, parzysty describes an even number or an even property. The phrase parzysta liczba refers to an even number. Corresponding phrases show the genitive, dative, and locative forms: parzystej liczby means “of an even number,” and na parzystej liczbie means “on the even number.” These examples illustrate how the form parzystej accompanies feminine nouns when the sentence requires those particular cases.

Related terms include parzystość, which denotes the property of being even (parity), and its opposite nieparzystość (oddness). The simple, base adjective parzysty has other inflections such as parzysta (nominative feminine) and parzyste (neuter or plural), illustrating Polish agreement rules across gender, number, and case.

Usage notes: parzystej is not a standalone noun or concept; it is a grammatical form used to modify feminine nouns in specific cases. Understanding parzystej helps parse phrases referring to even numbers and other feminine-noun constructions in Polish grammar.
