the.com/presidency

means The office and term of serving as president — the top executive job in a republic, held for a fixed stretch and watched by basically everyone the whole time.

from From Latin 'praesidere' — 'to sit before' or 'preside over' — built from 'prae' (before) plus 'sedere' (to sit). The image is literal: the one who sits at the front, overseeing the room. English picked up 'president' in the medieval period for anyone presiding over a council or assembly, and only later — notably with the founding of the United States — did it narrow into the title for a republic's chief executive, with '-ency' tacked on to name the office and its term rather than the person.
