Actor’s prompt (3)
I believe the answer is:
cue
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">actor's prompt</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for cue that I've seen before include "Hint, prompt" , "Catchword" , "Reminder to do something" , "Signal to players" , "Signal for player" .)
