Questions & Answers about Ich weiß, dass die Police diesen Fehler nicht ausschließt.
Why does this sentence use die Police instead of die Polizei?
Die Police is a false friend! It means an insurance policy or contract, not the police force. If you wanted to talk about law enforcement, you would use die Polizei.
ausschließt is a separable verb (ausschließen). Why isn't the prefix aus separated at the end of the sentence?
Because this is a subordinate clause introduced by dass. In a subordinate clause, the conjugated verb is pushed to the very end. When a separable verb is forced to the end like this, the prefix and the conjugated stem reunite into a single word.
Why is the demonstrative pronoun diesen used here instead of dieser?
The word Fehler (error or mistake) is a masculine noun. Because the error is the direct object being excluded by the policy, it must take the accusative case, making it diesen Fehler.
Could I put nicht earlier in the sentence, for example right after dass die Police?
Placing nicht right after Police would sound unnatural here. In German, nicht typically goes right before the specific element it negates. Since it negates the entire action of the verb (ausschließen), it belongs right before the verb at the end of the clause.
