if im gonna say "the man is a doctor"

is it better to say "bu adam bir doktor" or "bu adam doktor" or "adam doktor" which one is right?

Bu adam bir doktor : This man is a doctor

Bu adam doktor : This man is a doctor

Adam Doktor: Man is a doctor

The meaning of Turkish and English phrases does not match one to one. Turkish phrases can be used during different situations. Like this:

Bu adam bir doktor! Fakat aynı zamanda bir şarkıcı. : This man is a doctor! But at the same time a singer. So in this context you emphises that being a doctor is a difficult thing but he can also sing mean while.

Bu adam doktor, şu adam ise pilot: This man is a doctor, that man is a pilot. So here we compared two man.

Adam doktor, tabii ki yoğun olacak: The man is a doctor, ofcourse he will be busy.

I hope those will help.

Best.
