What is the correct way to address a President during formal introductions?

The proper way to address a President during formal introductions is by using their title only or by combining their title with their last name. This form of address demonstrates respect and acknowledges the importance of the office. Using the title "President" conveys the formal rank and authority of the individual, while including the last name ensures that the specific person is recognized.

In formal contexts, formality is key, and options that might seem more casual, such as using first names or informal titles, do not convey the appropriate level of respect expected in such situations. Addressing someone simply as "Mr. President" or "The President" also lacks the complete structure of a formal address, which typically includes the title in conjunction with the surname, reinforcing the importance of etiquette in official interactions.
