doctor

A doctor is a person that has succeeded in research-related postgraduate studies of an extended period. Also known as a "doctor of philosophy".

Some professions such as medical practitioners, dentists, chiropractors and optometrists have more recently corrupted use of the term for their own personal ends.

"I am a doctor."

"Good, can you help me with my ingrown toenails?"

"No sorry, I'm a REAL doctor."
