He was the dean at a college

Dlaczego przed dean jest the? To nazwa funkcji. Co myślicie?

The dean could be the top dean od that college.

Mr. Bertollucci was the dean of the press corps at the White House. After the war, he quit journalism. Just before retirement, he was the dean at a few colleges.

Clinton was a lousy president, but he was nonetheless president (of the United States). He served two terms in office or, in the role of president of the US, but in my book, he was never a president (of the United States).

When you get the difference in meaning, it will be time to follow the convention of capitalizing "P/president", "P/prime M/minister"… in all the right places.
