Well. My hypothesis is the Scientific method. My knowledge confirms this hypothesis. The scientific method is the method you are looking for
After 1660 in England<span>, when women first started to appear on stage, the terms </span>actor<span> or </span>actress<span> were initially used interchangeably for female performers, but later, influenced by the French </span>actrice<span>, </span>actress<span> became the commonly used term for women in theatre and film. The etymology is a simple derivation from </span>actor<span> with "-</span>ess"<span> added.</span><span> However, when referring to more than one performer, of both sexes, </span>actor<span> is preferred as a gender-specific term for male performers. </span>Actor<span> is also used before the full name of a performer as a gender-specific term.
Hope this is of help to you, and happy studying~!
