Er gedenkt des Verstorbenen.
English: He commemorates the deceased.
The 'Genitivobjekt' is an object in a German sentence that is required by certain verbs and stands in the genitive case. It answers the question 'wessen?' (whose?).
You use the genitive object in German when a verb specifically requires its object to be in the genitive case. This is less common in modern German, but some verbs still use it. It often expresses possession or a close relationship.
Er gedenkt des Verstorbenen.
English: He commemorates the deceased.
Wir bedürfen deiner Hilfe.
English: We need your help.
Sie erinnert sich des schönen Tages.
English: She remembers the beautiful day.
Er schämt sich seiner Worte.
English: He is ashamed of his words.
