<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">arabian port</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for aden that I've seen before include "foreign climes" , "Red Sea port" , "Dean is in the Yemen, strangely" , "Dean out in the seaport city" , "somewhere on the Arabian peninsula" .)
