filmu

Filmu is the genitive singular form of the Polish noun film, which denotes a motion picture. In Polish, nouns decline by case, number, and gender, and film has a full set of inflected forms: nominative singular film, genitive singular filmu, instrumental singular filmem, nominative plural filmy, genitive plural filmów, dative plural filmom, and locative plural filmach. The form filmy is used for certain counts or cases, while filmu specifically marks the genitive singular.

Usage and examples include expressing possession, relationship, or specification of a subset. Examples: bez filmu means without the film, gatunek filmu means the genre of the film, and historia filmu means the history of the film. The genitive singular filmy is not interchangeable with nominative filmy or genitive plural filmów, which have different functions and meanings within sentences.

In a dictionary or grammar discussion, filenu would be described as the genitive singular of film, distinct from the other forms listed above. Its appropriate use depends on the syntactic role the noun plays in a sentence, particularly after prepositions that govern the genitive or in noun phrases that require a possessive or relational meaning.
