In Romanian, 'pe' marks the direct object when it refers to a specific person or thing. Since 'care' is the object of the verb, it needs the marker.
No, 'care' is for subjects or objects. If it's a direct object, use 'pe care'. If it's genitive, use 'al cărei'.
Always before a subordinating conjunction if the subordinate clause follows the main one.
In Romanian, the clitic acts as a grammatical 'hook' that links the displaced object back to the verb. Without it, the sentence feels incomplete to a native ear.
Not at all! It's actually very common in spoken Romanian to show emotion, contrast, or to answer questions efficiently.
