Zwinnego

Zwinnego is the genitive singular masculine form of the Polish adjective zwinny, which means nimble, agile, or dexterous. In standard usage it functions as a descriptive modifier for masculine nouns in the genitive case. Because Polish adjectives agree with the noun in gender, number, and case, zwinnego appears specifically when the noun is masculine singular in genitive or, in contexts where the masculine noun is the object, in the accusative as well, since the accusative of masculine animate nouns often mirrors the genitive.

The form is most commonly seen with masculine nouns, for example zwinnego kota (a nimble cat, where kota is genitive singular) or zwinnego psa (a nimble dog). It can also occur in sentences that require the genitive for other reasons, such as after verbs that govern genitive, for instance brak zwinnego psa (a lack of a nimble dog) or brakuje zwinnego kota. In these contexts, zwinnego agrees with the head noun in gender and case, while the gender of the noun determines the rest of the agreement.

Because zwinnego is a specific inflected form, it should not be confused with other gender forms of zwinny, such as zwinna (feminine singular nominative) or zwinne (neuter singular or plural). The base adjective zwinny is used to describe agile qualities across genders, with each form adapting to the grammatical category of the noun it modifies.
