naszego

Naszego is the genitive singular form of the Polish possessive determiner nasz, meaning "our." It is used before masculine personal or neuter nouns in the genitive case, typically to indicate possession by the speaker and others in the group.

Morphology and usage notes: The possessive nasz changes with gender and case. In genitive singular, masculine personal and neuter nouns take naszego, while feminine nouns take naszej. Plural forms include naszych (genitive and some other cases). The form nasze, nasza, napotykane in nominative, changes to naszego, naszej, or naszych depending on gender and case. The choice of form depends on the gender and number of the possessed noun, not the possessor.

Examples:

- dom naszego syna = our son’s house

- okno naszego domu = the window of our house

- szkoła naszego miasta = the school of our city

These phrases illustrate how naszego marks possession by "our" when the possessed noun is in genitive as part of a larger noun phrase.

Etymology and typology: Nasz comes from the Slavic possessive family meaning "our." Naszego is the standard genitive singular form used in modern Polish. This form is common in both written and spoken language and appears in everyday expressions, official writing, and literature.
