"Good morning, I am a doctor."
Translation:Dzień dobry, jestem lekarzem.
I find it really confusing when duolingo says "Another correct solution: Dzień dobry, jestem lekarką" and makes me think that I have not given the best solution. (I gave dzień dobry jestem lekarzem - the only thing I can see wrong is the "D".) For anyone else who comes here, lekarką is of course the instrumental for a female doctor.
