I know "überlegen" means to ponder, to think about, to consider etc. And I definitely know that the following sentence is in imperative mood. But what's the definition when a policeman says:
Überlegen Sie zuerst!
For example, among these safety recommendations (Ratschlägen):
- Überlegen Sie zuerst!
- Öffnen Sie die Wohnungstür nicht!
- Unterschreiben Sie nichts!
- Informieren Sie die Polizei!
Sie
in here must be the object of the sentence in accusative case because I didn't find the verb überlegen as a reflexive verb in Duden dictionary. So it's not a subject and therefore we can't interpret it as to think about, to ponder. Any guide is appreciated.
