Forms

ἐπῐδήμῐος (epidḗmios) m or f (neuter ἐπῐδήμῐον); second declension[1]

Etymology

It is formed from Ancient Greek ἐπί (epí) + δῆμος (dêmos, “people, country”) + -ιος (-ios).[1][2][3] Chæréphon cites Mycenaean Greek o-pi-da-mi-jo, a plural, under this word.[4]

Earliest recorded meaning

In Homer it means “among one's own people”: in the Iliad a civil war is a πόλεμος ἐπιδήμιος, and plunderers of their own countrymen are ἐπιδήμιοι ἁρπακτῆρες; in the Odyssey a man's father is said to be at home.[3][5][6]

Semantic evolution

From “in the country” the word came to mean “staying in a country” as a visitor: Herodotus uses it of resident merchants, and Apollonius of Rhodes of settling in a place.[5][6] In Apollonius it also describes a custom of the land, the lack of shame about lovemaking in public.[6][5][7]

The Hippocratic writers called a disease that is widespread among a people ἐπιδήμιος, “prevalent, epidemic”.[5][7] In Plutarch it means common, commonplace.[5] Late Greek used ἐπιδήμια θύειν for a sacrifice for someone's arrival.[5] The Byzantine lexica gloss it as ἐμφύλιος (emphúlios) “of one's own people” and κοινός “common”.[8][9]
