—-#2) President is rarely used as an honorific.
While we hear the President of the United States referred to in the press as President (Name) in the media … this is not a form of address.
The POTUS is addressed as ‘Mr. President’. The President’s name is not used in direct oral or written address. The President, if he were to introduce himself would do so like anyone else – as ‘(Full Name)’.
I’ve never encountered a corporate president who wanted to be addressed as ‘President (Name)’ rather than ‘Mr./Dr./etc. (Name)’.
Presidents of universities are addressed in writing as ‘Dr. (Full Name)’ and identified after their name as ‘President of ABC University’. It’s possible someone would say orally (and informally) ‘the President will be here in five minutes’ or ‘President may I show you to your seat?’ But formally the university president is directly addressed as ‘Dr./Mr./Mrs./Ms. (Name)’. This president would also introduce himself as ‘(Full Name)’.
#3) Headmaster is used as an honorific in oral conversation or in a salutation. Use this form:
—-—-Dr./Mr./Ms. (Full Name)
—-—-Headmaster (or President)
—-—-(Name of School)
—-Conversation or Salutation:
—-#4) All this said, if he wants to be addressed as President Wilson … I would call him ‘President Wilson’. It is his name and it is his right to be addressed as he wishes to be. But it’s odd.
