I believe the answer is:
yemen
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">aden's country</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 yemen that I've seen before include "Saudi neighbour" , "Arabian republic, capital Sanaa" , "Republic sited on the SW corner of Arabia" , "Country to south of Saudi Arabia" , "Country between the Red Sea and the Gulf of Aden" .)
