Etymology

It is borrowed from Ancient Greek πάνδημος (pándēmos, “of or belonging to all the people, public”).[1][2][3] The Greek word is built on παν- (pan-, “all”) and δῆμος (dêmos, “land, people”).[2]

Earliest recorded meaning

It is first found in Ammianus Marcellinus, who applies it to lues, a plague: one affecting all the people, an epidemic.[3][4][2]

Semantic evolution

It means “affecting the whole people, general”;[3][4] French and Italian dictionaries render it as “endemic” or “epidemic”.[5][6] Conte marks it as medical and adds an example from the Latin Oribasius.[6]
