Etymology
Origin of doctor
First recorded in 1275–1325; Middle English docto(u)r, from Anglo-French, from Latin, from doc(ēre) “to teach” + -tor -tor
Explanation
You see doctor, and you think of someone doing good — like the medical doctor who saves lives. However, a person who doctors or tampers with a document is adding something wrong or harmful to it, like a lie. Doctor is the Latin word for "teacher," which makes sense since your doctor is often the one teaching you about how to take care of your body. Anyone who has a PhD, be it in English or Egyptology, is also referred to as a doctor because she holds a doctorate degree. But beware, there's also a market out there for doctored, or tampered-with diplomas, where you can buy a fake degree to call yourself a doctor.
