appointment or date?

You can have an appointment with your doctor or your dentist but we don't normally say: I have a meeting with my dentist. Instead we say: I have an appointment at the doctor's or I have a dentist's appointment. Another word that is very similar to appointment is the word date. A date usually is a private meeting with another person. So, when you say: "I have a date with my boss." it means you will see your boss privately. You probably know the term "blind date". That's a rendezvous with a person you have never seen before so you meet him or her for the first time. OK, that's it for now. I must go because I have an appointment.
