Domina

Domina is a title used for a dominatrix or domme derived from Latin. It is used in many languages globally and it can mean: lady of the house, mistress, dominant female, lady of honor, the head of a nunnery, or a noble lady who held a barony. The Male version of Domina is Dominus.

The word has roots in the word "domina" which was not BDSM related, but was more for addressing a lady, a wife or a mistress in Roman Antiquity.
