A dominatrix (plural dominatrices or dominatrixes) or mistress is a woman who takes the dominant role in bondage and discipline, dominance and submission or BDSM. A common form of address for a submissive to a dominatrix is "mistress", "ma'am", "domina" or "maîtresse". Note that a dominatrix does not necessarily dominate a male partner; a dominatrix may well have female submissives.
The term "domme" is a coined pseudo-French female variation of the slang dom (short for dominant). It stems from the Latin words "dominus" = master, "domina" = mistress. The pronunciation is identical to the term "dom", by analogy to one-syllable French-derived words like femme or blonde.
As fetish culture is increasingly becoming more prevalent in Western media, depictions of dominatrices in film and television have become more common.
