means The state of being physically present in a place, or the felt quality of someone's bearing that fills a room even when they say nothing.

from From Latin praesentia, "a being before," from praesens — itself prae- ("before, in front of") plus a form of esse ("to be"). So at root it means simply "being in front of," and it arrived in English through Old French presence in the medieval period. The richer sense — a charisma, an aura, a weight you carry — grew out of that literal one: to be truly before someone, not just nearby.
