Give an example of a courtesy title?

A courtesy title is a title used to address someone who doesn't actually hold that title. Here are some examples:

* Mr./Ms./Mrs./Mx. + Last Name: This is the most common courtesy title, used for adults regardless of their actual position or status. For example, you might address a teacher as "Mr. Smith" even though they are not officially a "Mister".

* "Doctor" + Last Name: This is used for individuals who hold a doctorate degree (Ph.D., Ed.D., etc.), even if they are not practicing physicians.

* "Professor" + Last Name: This is often used for university faculty members, even if they don't hold the official title of "Professor."

Examples in context:

* "Good morning, Doctor Jones." (Even though Dr. Jones may be a historian, not a medical doctor)

* "Can I speak to Professor Smith?" (Even though Professor Smith may be a teaching assistant, not a full professor)

* "Thank you for your time, Mr. Johnson." (Even though Mr. Johnson may not be a "Mister" in any official sense)

It's important to note that while using courtesy titles is polite, it's always best to use the correct and preferred title when possible. If you're unsure of someone's proper title, it's always okay to ask.
