Questions & Answers about Der Bürgermeister organisiert anlässlich der Einweihung einen feierlichen Empfang.
Why do we use der before Einweihung if it is a feminine noun?
Because the preposition anlässlich (on the occasion of) requires the genitive case. For feminine nouns like die Einweihung, the definite article changes to der in the genitive.
Could I place einen feierlichen Empfang before anlässlich der Einweihung?
It would sound unnatural. In German, adverbial phrases explaining why or when something happens (like anlässlich der Einweihung) typically come before the direct accusative object (einen feierlichen Empfang).
Why does the adjective feierlich take the -en ending here?
Empfang (reception) is a masculine noun acting as the direct object, so it is in the accusative case. After the masculine accusative indefinite article einen, the adjective feierlich must take the -en ending.
What is the root of the noun Einweihung?
It comes from the separable verb einweihen, meaning to inaugurate or to dedicate. Adding the suffix -ung turns it into a feminine noun representing the event itself.
