In the 21st century how is the noun word "President" defined

 

It is clear from my research that the definition of the noun word President has a direct relationship to the political aspect of the word, all the dictionary websites I found, define this noun word similarly, as both a President of a "Federal Republic" and a "Republic" where the President is a "ceremonial position," in addition to citing this noun word as connoting this noun word to refer to a corporation or company.

However, I've also included the websites Wikipedia and Britannica to cite the historical definitions of the noun word "President" which shows how this noun word has evolved .

I chose this noun word President due to the claims by the opposition to this administration, that the current POTUS is acting like a king, but as can be seen, all the definitions cite the aspect of "being in charge" when defined as the "President of a Federal Republic," with few examples of what the leader of a Federal Republic can do, since this blog offers only words plus meanings information, the scope of the acts of a President of a Federal Republic are not fully cited.

What I've presented proves that this noun word "President" has a vast scope when connoted as the "President" of a Federal Republic when specifically citing the US, and as such, does eliminate the aspect of a point of view to color this word with other definitions.
