Pronunciation
Forms
dominus m (genitive dominī, feminine domina); second declension[1] A syncopated domnus appears in inscriptions.[2][3] Medieval texts also write dompnus, especially as a title.[4]
Etymology
It is inherited from Proto-Italic *dom-o/u-no- (“of the house”), a derivative of the word for “house”, domus.[5][2][6] Pinault reconstructs Proto-Indo-European *dom-h₃n-o- (“one who profits from the house”) and compares Sanskrit दमूनस् (dámūnas-, “lord of the house”), but de Vaan doubts that the two go back to one inherited word.[5] Wiktionary gives both the Proto-Italic form and a reconstruction Proto-Indo-European *domHnos (“homeowner”).[1] Lewis & Short followed an older view connecting it with domō “to tame”.[3]
Earliest recorded meaning
Plautus uses it of the master of slaves.[5][2] Köbler dates Plautus c. 250–184 BC.[7]
Semantic evolution
In Classical Latin it was the master of a household or of slaves, an owner, and also the young master, the son of the house.[2][6] It was the manager of a troupe or of games, the host of a feast, a ruler or despot and, of gods, a lord, dominus nāvis was the master of a ship.[2] As a courtesy title it meant “sir”, and lovers used it as a term of endearment.[2]
In Christian Latin Dominus was the Lord, God.[1] Medieval writers used it of a vassal's lord, the emperor, the king and the holder of a seigniory, and dominus terrae was a territorial prince.[8] The shortened domnus was common as a form of address and as an ecclesiastical title.[4] It survives as Italian donno, Spanish dueño, Portuguese dono and Romanian domn.[1]
