Questions & Answers about Wir rufen den Arzt, falls es ein Notfall wird.
Why does the verb wird go at the very end of the sentence?
The word falls (in case) is a subordinating conjunction. Whenever you start a clause with falls, it acts like a kicker that sends the conjugated verb for that part of the sentence (in this case, wird) all the way to the end.
What is the exact difference between using falls and wenn in this sentence?
You could absolutely use wenn here, but falls is more specific. Wenn can mean "if" or "whenever." Using falls translates closer to "in case" or "in the event that." It strongly emphasizes that the emergency is just a possibility, not a certainty.
Why is it ein Notfall and not the accusative einen Notfall?
Normally, a noun following an action verb takes the accusative case because it's a direct object. However, the verb werden (to become) is a special linking verb, just like sein (to be). It equates the subject (es) with a new state or identity, so the noun following it must stay in the nominative case (ein Notfall).
Why do we use den Arzt in the first half of the sentence?
