Definition
- Noun:
- A title for a person who holds a doctorate: "Dr." is an abbreviation used as a title before the name of a person who has earned a doctoral degree, such as a Ph.D. (Doctor of Philosophy), Ed.D. (Doctor of Education), or D.Sc. (Doctor of Science).
- A title for a physician or dentist: "Dr." is also used as a title before the name of a person who is qualified to practice medicine, such as a medical doctor (M.D.) or a doctor of dental surgery (D.D.S.).
Usage Notes
- "Dr." is an abbreviation, not a word itself. It is always written with a period.
- It is used as an honorific title before a person's surname or full name.
- The context usually clarifies whether the title refers to an academic doctorate or a medical professional. When addressing someone directly, "Doctor" is used instead of "Dr." (e.g., "Hello, Doctor Smith").
