Re: Do we want to know the Doctor's secret?
Professors in college are sometimes called Doctors, and then you have specific types of Doctors.
Professors in college ARE doctors. They have doctorates in their field of study (generally a PhD). When in a teaching position a PhD is called a "Professor." Those without a doctorate who are in a teaching position are "Instructors."
