To be in charge of or lead a meeting, event, or organization; to sit or be positioned at the head.
From Latin 'praesidere,' combining 'prae-' (before) and 'sidere' (to sit). Literally meant 'to sit in front,' which evolved into the modern meaning of official leadership.
The Romans literally had someone sit in front—the word presided is geography made language, showing how physical positions of power became metaphors for actual authority.
