Questions & Answers about Weißt du, ob der Saal für heute Abend geschmückt ist?
Why does the sentence use geschmückt ist instead of geschmückt wird?
This is the stative passive (Zustandspassiv). It uses a form of sein (here, ist) plus the past participle geschmückt to describe a completed state. It means the work is already finished and we want to know the current condition of the hall. If we used wird (the dynamic passive), it would mean the hall is being decorated right now.
Why can't I use wenn instead of ob for "if"?
In German, wenn is used for conditions ("if X happens, then Y") or repeated events ("whenever"). ob is used for indirect yes/no questions, meaning "whether". Since the first part of the sentence is "Do you know...", you are asking a yes/no question about a fact, so you must use ob.
Why is the conjugated verb ist at the very end of the sentence?
The word ob is a subordinating conjunction. It introduces a subordinate clause (ob der Saal für heute Abend geschmückt ist), which forces the conjugated verb to the very end of the clause.
Why use heute Abend for "tonight" instead of heute Nacht?
