Dominant

A Dominant is the person of power or authority/control in a power exchange relationship who practices some form of domination,whether it be physical, mental, emotional or spiritual domination. The term can also be used to describe someone with a series of dominant personality traits.

It should be noted that in general usage, the word Dom is a short, gender non-specific replacement for the word Dominant. "Domme" (usually pronounced "dough-may") has come to indicate a female Dominant.
