Questions & Answers about Wegen des kaputten Ersatzteils haben wir eine Verzögerung.
How would I express this same idea using a full clause with weil?
You would say: Weil das Ersatzteil kaputt ist, haben wir eine Verzögerung. Notice how the nominalized phrase (wegen + genitive noun) expands into a subordinate clause with a subject (das Ersatzteil) and a conjugated verb at the end (ist).
Why does the adjective kaputt have an -en ending here?
It follows the rules of weak adjective declension. The preposition wegen requires the genitive case. Because the definite article des already clearly marks the genitive masculine/neuter case, the adjective just takes the standard weak ending -en.
Is the -s at the end of Ersatzteils a plural marker?
No, it is the genitive singular marker. Das Ersatzteil (the spare part) is a neuter noun, and masculine and neuter nouns usually add an -s or -es in the genitive case. If the sentence were plural, it would be wegen der kaputten Ersatzteile (because of the broken spare parts).
The lesson also mentions aufgrund. Could I use it instead of wegen here?
Absolutely. Aufgrund des kaputten Ersatzteils... means the exact same thing and also requires the genitive case. Aufgrund sounds slightly more formal or professional than wegen, making it very common in business correspondence.
Will I always hear Germans use the genitive with wegen?
In written and formal German, yes. However, in casual, everyday speech, native speakers frequently use wegen with the dative case instead: Wegen dem kaputten Ersatzteil... At the B2 level, you should write with the genitive but be prepared to hear the dative in conversation.
