Questions & Answers about Ich kaufe das Sofa, weil das Angebot gut ist.
Why is the verb ist at the very end of the sentence?
Weil (because) is a subordinating conjunction. In German, these types of connecting words force the conjugated verb (in this case, ist) to move to the very end of their clause.
Is the comma before weil mandatory?
Yes! Unlike in English where a comma before "because" is often optional, in German you must always use a comma to separate the main sentence (Ich kaufe das Sofa) from a subordinate clause (weil das Angebot gut ist).
Why didn't the article for das Sofa change since it is the direct object?
Because Sofa is a neuter noun. You are right that it is the direct object being bought, which puts it in the accusative case. However, neuter words use das for both the nominative and accusative cases, so the word doesn't change form like masculine nouns do.
What exactly does das Angebot mean in this context?
Das Angebot translates to "the offer" or "the deal". You will frequently see it used in German stores or advertisements to talk about items that are on sale or offered at a good price.
