Pronunciation

  • 10th-century Byzantine: /yˈci.a/[1]

Forms

οἰκῐ́ᾱ (oikíā) f (genitive οἰκῐ́ᾱς); first declension[1]

Etymology

It is formed from Ancient Greek οἶκος (oîkos, “house”) + -ία (-íā),[2][3] or, in Wiktionary's analysis, from the verb οἰκέω (oikéō, “to dwell”) with the same suffix.[1] Cretan and Locrian have ϝοικία (woikía), with the initial /w/.[4][2] The Homeric neuter plural of the same shape, “dwellings”, matches a Sanskrit word for “house, village” in form, but Beekes, following Schindler, takes the two as separate innovations.[2]

The base noun goes back to Proto-Hellenic *wóikos, from Proto-Indo-European *wóyḱos (“settlement”),[1][2] which Beekes takes as an action noun, “settlement”, from a verb meaning “to sit down, settle, enter”.[2] Cognate with Mycenaean Greek wo-ko, Latin vīcus (“village, quarter”), Sanskrit वेश (veśá, “house”) and Gothic 𐍅𐌴𐌹𐌷𐍃 (weihs, “village”).[1][2]

Earliest recorded meaning

Homer has only the neuter plural τὰ οἰκία, dwellings, also of the nests of wasps, bees and an eagle.[2][5] The feminine singular, a dwelling or house, appears first in the iambic poets Archilochus and Semonides.[5]

Semantic evolution

In Herodotus, Thucydides and Attic prose it is the ordinary word for a house, much more frequent in comedy and prose than οἶκος (oîkos).[4][5] Attic law distinguished the two: οἶκος was the whole estate a man left, οἰκία only the dwelling-house, as Xenophon states.[4] It also means the household or domestic establishment (Plato, Demosthenes), which Aristotle treats as more primitive than the city, and the family a person descends from (Herodotus, Thucydides).[4][5]

In the New Testament it is a house as a building and the household living in it.[6]

Vernacular Greek of 1100–1669 had it as a learned word, and Modern Greek οικία (oikía) is a formal, learned word for a residence.[7][8]

  • 5th century BC – Herodotus and Thucydides use it for a house, a household and a family.[5][4]
