<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">two-part</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 dual that I've seen before include "Twofold" , "Consisting of two parts" , "Road with central division" , "Having two distinct functions" , "Double" .)
