Superintendent → It is formed from "super-" (meaning above or over) and "intendere" (meaning to stretch or direct). The word refers to someone who directs or oversees from a position of authority, thus being above others in a supervisory role.
Think of someone who is 'above' ('super-') and 'directing' ('intendere') others — that's why a superintendent is someone who oversees and manages.
