  • 4th-century AD Koine: /e.pi.ðiˈmi.a/[1]
  • 10th-century Byzantine: /e.pi.ðiˈmi.a/[1]

Forms

ἐπῐδημίᾱ (epidēmíā) f (genitive ἐπῐδημίᾱς); first declension[1] Ionic ἐπιδημίη (epidēmíē), in the Hippocratic writings.[2][3] Doric ἐπιδαμία (epidāmíā), on Rhodes.[3][1]

Etymology

It is formed from Ancient Greek ἐπιδημέω (epidēméō, “to be at home, to stay in a place”) + -ία (-íā).[1][4] The verb belongs with ἐπίδημος (epídēmos, “living at home”), which is ἐπί (epí) with δῆμος (dêmos, “people, district”),[5][6][7] like ἔνδημος (éndēmos) and ἀπόδημος (apódēmos, “abroad”).[6]

Earliest recorded meaning

Its first record is in the Constitution of the Athenians ascribed to Xenophon, for the stays of the allies in Athens, and Plato uses it for a stay in a city.[3][2]

Semantic evolution

The word meant a stay or sojourn in a place, a visit by a foreigner, and in Menander a homecoming from abroad.[8][3] In the Hippocratic writings it is the prevalence of a disease among a people, and the title of the seven books of the Epidemics.[3][6] Aelian applies it to rain, and in the imperial period it is the visit of an emperor, in Herodian and an inscription from Thyatira.[3] Most of its recorded uses fall in the 2nd century AD.[2] A Christian writer calls a human life the sojourn of the flesh in this world.[9]

It was borrowed as Latin epidemia, and later were the Russian and Bulgarian words for an epidemic.[1] English epidemic comes from French épidémique, which goes back to Medieval Latin.[7] Medieval vernacular Greek also used it for a raid.[10] In Modern Greek the learned επιδημία (epidimía) is an outbreak of disease, and figuratively a run of unpleasant events.[11]
