domus

Etymology and origin of the Latin word domus

History

Pronunciation

  • IPA (Classical): [ˈdɔ.mʊs][1]
  • IPA (Ecclesiastical): [ˈdɔː.mus][1]

Forms

domus f (genitive domūs or domī); irregular, variously declined, fourth declension, second declension[1]

Etymology

It is inherited from Proto-Italic *domo-, from the Proto-Indo-European root noun Proto-Indo-European *dṓm (“house”);[2][1] Wiktionary traces this to the root *dem- (“to build”).[1] De Vaan explains the feminine gender from the original root noun: Old Latin has mainly o-stem forms, and the fourth-declension forms may be an attempt to fit a feminine noun to a more usual pattern.[2] It is cognate with Sanskrit दम (dáma-), Ancient Greek δόμος (dómos), Lithuanian nãmas and Old Church Slavonic домъ (domъ), all "house".[2] It is also related to dominus.[1]

Earliest recorded meaning

De Vaan dates it from Livius Andronicus (280/260–before 200 BC).[2][3] Plautus uses it for the house where one lives, with the old genitive domī.[4][5]

Semantic evolution

It was the house as a home, the seat of a family, and in the city a large private house as distinct from apartment blocks.[4][6] Poets extended it to the homes of birds and animals, the shells of molluscs, and the tomb as the home of the dead.[4] It could mean one's home town or country, and the seat of an activity: Cicero calls Athens the home of learning.[4] It also meant the people of a house, the household and family, and a school of philosophers.[4] Idioms built on domī and domō meant "in oneself" and "from one's own resources".[4]

In medieval Latin a domus was a court or royal household, a dynasty, a bishop's residence, a farm or manor, and, as domus Deī, a church, monastery or hospice; it could also mean a cathedral.[7][8] From this sense come Old Frisian dōm and Old High German tuom, German Dom.[3]
