<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">word on the way out?</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 adieu that I've seen before include "Goodbye, mon ami!" , "cheers" , "Adios, Arrivederci" , "Au revoir (to a kind friend?)" , "I'm away (in France?)" .)
