Domus

In ancient Rome, the domus (plural domūs, genitive domūs or domī) was the type of house occupied by the upper classes and some wealthy freedmen during the Republican and Imperial eras. It comes from the Ancient Greek word domi ("δομή") meaning structure since it was the standard type of housing in Ancient Greece. It could be found in almost all the major cities throughout the Roman territories. The modern English word domestic comes from Latin domesticus, which is derived from the word domus. The word dom in modern Slavic languages means "home" and is a cognate of the Latin word, going back to Proto-Indo-European. Along with a domus in the city, many of the richest families of ancient Rome also owned a separate country house known as a villa. While many chose to live primarily, or even exclusively, in their villas, these homes were generally much grander in scale and on larger acres of land due to more space outside the walled and fortified city.
