Questions & Answers about Nach dem Abschluss träumt sie von der großen Feier.
Why does the sentence use von der when Feier is a feminine noun (die Feier)?
The verb träumen (to dream) pairs with the fixed preposition von to express what someone is dreaming about. The preposition von always forces the noun that follows it into the dative case. Since Feier is feminine, its article changes from die to der in the dative.
Why does the adjective groß have an -en ending here (großen)?
This is because the phrase is in the dative case. Whenever you have a definite article (like the dative der here) in front of an adjective, that adjective must take an -en ending in the dative case, regardless of the noun's gender.
Why is it Nach dem Abschluss instead of Nach der Abschluss?
The word Abschluss is masculine (der Abschluss). Just like von, the preposition nach (after) is a "dative preposition," meaning it always forces the noun following it into the dative case. In the dative, the masculine article der changes to dem.
Why is the word order träumt sie rather than sie träumt?
