doctor

A physician; a member of the medical profession; one who is trained and licensed to heal the sick or injured. The final examination and qualification may award a doctor degree in which case the post-nominal letters are DO, DPM, MD, DMD, or DDS in the US, or MBBS or BDS in the UK.

How to use

In formal and informal contexts, the term 'doctor' is used to refer to a medical professional who has earned a doctoral degree. However, it's worth noting that in the UK, the term 'doctor' is often used as a courtesy title for medical professionals who have not earned a doctoral degree. For example, 'I'm going to see the doctor' is a common phrase in British English, whereas in American English, it would be more accurate to say 'I'm going to see my physician' or 'I'm going to see a doctor.' This nuance highlights the importance of considering regional variations in language use.
