Pronunciation

  • 5th-century BC Attic: /ěː.so.dos/[1]
  • 4th-century AD Koine: /ˈi.so.ðos/[1]
  • 10th-century Byzantine: /ˈi.so.ðos/[1]

Forms

εἴσοδος (eísodos) f (genitive εἰσόδου); second declension[1] Also ἔσοδος (ésodos), in Pindar, Herodotus, Thucydides and Pausanias.[2][3]

Etymology

It is from Ancient Greek εἰς (eis, “into”) + ὁδός (hodós, “way”).[1][4][5] Compare ἔξοδος (éxodos, “way out”) and δίοδος (díodos, “passage”).[5] For ὁδός (hodós) Beekes reconstructs Proto-Indo-European *sod- (“course”).[6]

Earliest recorded meaning

In the Odyssey it is the narrow entrance of a harbour.[4][2]

Semantic evolution

In Classical Greek it was a place of entry: the entrance of a temple in Euripides, a mountain pass into Greece in Herodotus, the side entrance of the chorus in the theatre in Aristophanes, the door of a lawcourt in Aristotle.[3][2] Pindar uses it figuratively for the ways to glory.[3] It was also the act of entering, entry into the lists at the games, the bringing of a suit into court, the right of access to a king, and a visit, including a doctor's visit in Galen.[3] Polybius uses it for revenue, opposed to ἔξοδος (éxodos) “expenditure”, and Vettius Valens for a study or method.[3] The Septuagint has it for an entrance hall and for an influx, and Hermas calls Christ the only entrance to the Lord.[7][8]

Medieval Greek used it for the Great Entrance of the liturgy, for the feast of the Entry of the Virgin into the Temple, and for income.[9] Modern Greek είσοδος (ísodos) is a learned word: the entrance and the act of entering, with an admission sense modelled on French entrée and a computing sense on English input.[10]
