what is the definition of president?
A president is the leader of a country or a division or part of a country, typically a republic, a democracy, or a dictatorship. The title president is sometimes used by extension for leaders of other groups, including corporate entities and social groups. Etymologically, a president is one who presides (from Latin prae- before + sedere to sit; giving the term praeses). Originally, the term referred to the presiding officer of a ceremony or meeting (i.e., chairman), but today it most commonly refers to an executive official.
