Does the word doctor come from Greek?

Yes, the word "doctor" comes from the Greek word "didaskalos," which means "teacher." The word was first used in the 13th century to refer to a person who had a doctorate degree, which was the highest academic degree at the time. Over time, the word "doctor" came to be used more broadly to refer to any person who had a high level of education and expertise in a particular field, such as a medical doctor, a lawyer, or a professor.
