pisarza
"Pisarza" means "writer" (genitive or accusative singular form) in Polish.
Here, 'pisarza' is used in the genitive case in Polish to indicate possession or relationship, meaning 'of the writer'.
Książka napisana przez tego pisarza zdobyła wiele nagród.
The book written by this writer has won many awards.
In this sentence, 'pisarza' is again in the genitive case, showing possession, as it describes the style belonging to the writer.
Podziwiam styl tego pisarza, jest naprawdę wyjątkowy.
I admire the style of this writer; it is truly exceptional.
Here, 'pisarza' is employed in the accusative case because it is the direct object of the verb 'to meet'.
