<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">person in a cast</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for actress that I've seen before include "Garland perhaps" , "one with a particular role?" , "One playing" , "One on stage" , "Female stage-player" .)
