Questions & Answers about Warum hast du denn die Leute auf dem Zebrastreifen gefährdet?
Why is the past participle of the verb here just gefährdet instead of gegefährdet?
The infinitive of the verb is gefährden (to endanger). Because it already starts with the inseparable prefix ge-, it doesn't take an extra ge- when forming the past participle. Verbs starting with be-, ver-, er-, and ent- follow this exact same rule.
How does the word denn change the meaning of this question?
In this sentence, denn acts as a modal particle rather than a conjunction meaning "because". It adds a tone of surprise, disbelief, or urgency to the question. In English, we often capture this feeling by adding "on earth" or "tell me" to the sentence.
Even if the people and cars were moving, why do we use the dative auf dem Zebrastreifen instead of the accusative auf den Zebrastreifen?
auf is a two-way preposition. We use the accusative when asking "Where to?" (wohin?) to show a change of location or a destination. Here, the action of endangering the people happened entirely at the location of the crossing. Since it answers "Where did the event happen?" (wo?), we use the dative case.
Is Zebrastreifen the standard word for a crosswalk in German?
