Questions & Answers about אני מצפה ממך לתשובה כנה.
מצפה comes from the verb לצפות.
In this sentence, it means to expect. Depending on context, לצפות can also mean to look forward to, but here the meaning is clearly expect.
So אני מצפה... means I expect... or I am expecting....
Yes. That is a very common use of the same verb.
For example, אני מצפה לחופשה would usually mean I’m looking forward to the vacation.
In your sentence, though, the tone is not about pleasant anticipation. It is about expecting something from someone, so expect is the better translation.
