I’m guessing you’re referring to the Latin doctore, which means teacher, and how it’s different from medicus, which means medical doctor or at least something much like it. The only place I’ve seen doctor used in English to mean doctore is in Catholic contexts. But in English using the title Doctor is assumed to mean medical specialist in general circumstances. Any Ed.D that stands up when the flight attendant asks, “Is there a doctor on the plane?” deserves a scolding at the very least. Interestingly every single American with any kind of a technical Ph.D that I’ve ever met goes by first name and doesn’t balk at being called mister in all but the most formal circumstances (Germans are an entirely different matter). It’s the ones with Ph.Ds in things like English that get demanding about being called doctor in everyday life.
