domus (plural domus)
For Proto-Italic *domos, from Proto-Indo-European *dṓm (“house, home”), from root *dem- (“to build”). Cognates include Ancient Greek δόμος (dómos), Albanian dhomë (“a chamber, a room”), Avestan 𐬛𐬀𐬨- (dam-) Sanskrit दम (dáma), Proto-Slavic *domъ and further to English timber. At least indirectly cognate to Latin dominus.
The feminine gender is probably due to the original root noun; attempts to transfer it to the 4th declension are due to 2nd declension feminines being unusual outside of tree names. Some manuscripts of Plautus show forms in dem-; De Vaan (2008) doubts their authenticity.
domus f (genitive domūs or domī); irregular, variously declined, fourth declension, second declension
Fourth/second-declension noun, with locative.
