niektórej
The Polish word "niektórej" is the genitive singular feminine form of the indefinite pronoun "niektóry." This pronoun translates to "some" or "certain" in English and is used to refer to an unspecified person or thing from a larger group. The genitive case in Polish is often used to express possession, the absence of something, or as the object of certain prepositions. Therefore, "niektórej" would appear in sentences where it modifies a feminine noun in the genitive case, indicating "of some" or "of a certain" feminine noun. For example, it might be used in a phrase like "bez niektórych przyjaciół" (without some friends) or "historii niektórych kobiet" (the stories of some women). The pronoun "niektóry" itself has different forms depending on the gender, number, and case of the noun it modifies, with "niektórej" being a specific inflectional form. Its usage is integral to conveying indefiniteness and specificity within a broader context in Polish grammar.
