Dominus

'Lord, Master, Baron.'

The masculine form of 'domina.'

< Not to be associated with; 'deus' meaning; 'god.' >

Dominus is the Roman title for a lord, or master. Given to those holding higher positions of state or imperial appointment, and to the heads of an estate or baronetcy. The term derives from the Proto-Italic *dom-o/u-no- meaning: "he of the house," referencing back to the Proto-Indo-European root: *dem- meaning: "to build," through domus.
