Forms

praeses m or f (genitive praesidis); third declension[1]

Etymology

It is from Latin prae- (“before”) + sedeō (“to sit”), a root noun in *-se(d)s like obses (“hostage”): one who sits in front.[2][3][1] De Vaan traces sedeō to Proto-Italic *sed-ē- (“to be seated”) and Proto-Indo-European *sed-eh₁- (“to be seated”).[4] Isidore derived it instead from praesum (“to be at the head”).[3]

Earliest recorded meaning

Köbler dates it from Plautus,[5] whose Rudens sends two guards home from their post.[2]

Semantic evolution

It is a guardian or protector, as Cicero calls the tribune of the plebs the guardian of liberty and the senate the guardian of the state; it is used of tutelary gods, as Mercury the protector of youth, and of abstract things, as Celsus' medicine, the art that guards human health.[2][6] Under the Empire it becomes a general term for any provincial governor: Tacitus speaks of Vitellius as governor of Syria, and a jurist explains that proconsuls and imperial legates are all called by it.[2] Church Latin glosses it president, chairperson.[7] In Medieval Latin it is a provincial governor, a Carolingian or feudal count, the mayor of the palace, or a margrave or duke.[8]
