Pronunciation

  • 5th-century BC Attic: /oi̯.kuː.mé.nɛː/[1]
  • 4th-century AD Koine: /y.kuˈme.ni/[1]
  • 10th-century Byzantine: /y.kuˈme.ni/[1]

Forms

οἰκουμένη (oikouménē) f (genitive οἰκουμένης); first declension[1] Also οἰκεομένη (oikeoménē), with the vowels uncontracted.[1]

Etymology

It is the feminine present passive participle from Ancient Greek οἰκέω (oikéō, “to inhabit”), used as a noun by leaving out γῆ (gê, “land, earth”): “the inhabited land”.[1][2][3] The verb is formed from οἶκος (oîkos, “house”).[4]

Earliest recorded meaning

It is used as a noun from the 5th century BC: BDAG cites it from Herodotus on, and GLAUx finds it in Thucydides, Sophocles and Euripides.[2][5] At first it meant an inhabited region.[6]

Semantic evolution

In Demosthenes it is the Greek world, set against the lands of the barbarians.[6] Aristotle uses it for the whole inhabited world, including non-Greek lands such as Ethiopia, India and Scythia, as opposed to regions that may be uninhabited; the treatise On the Cosmos counts Asia, Libya and Europe as “this” world, and speaks of other worlds in the plural.[6] Greek geographers drew it as a circle bounded by Oceanus, a picture Herodotus already criticised.[7]

In Hellenistic Greek it could mean the whole world, and a papyrus flatters a Ptolemy as ruling all of it.[6] Under Rome it became the Roman world: inscriptions call Nero the saviour and benefactor of the world, and Luke and Acts use the word in this sense.[2][6] The New Testament also uses it for the inhabited earth as against the heavens and the underworld, and Hebrews speaks of “the world to come”.[2][6]

From the 4th century AD the derived adjective οἰκουμενικός (oikoumenikós) became a Church term, as in the ecumenical councils.[4] In Byzantine Greek the noun meant the civilised world, above all the empire, and medieval vernacular texts use it for the earth, for all mankind and for the whole Christian world.[1][8] It lives on as the learned Modern Greek οικουμένη (oikouméni), the whole earth.[3] Latin oecumene and the English ecumene are borrowed from it, and ecumenical comes through Latin from the adjective.[9][1][10]
