The literal meaning of "dominus" is master of a house. Secondary meanings are master or lord.
Latin is a tough language to master, and translations can be difficult. There are two Latin words for sportsman, Latro and Athleta.
Possible translations of "power" into Latin are vis(vis, f.) for strength or energy; potestas(-tatis, f.) for ability or control, and even posse(n., the infinitive of the verb meaning "to be able").
It is Latin in origin from the word Dominus meaning lord or master. Source: thefreedictionary.com
