I believe the answer is:
rural
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not urban</span>' is the definition.<br/ ><span class="explanation-format__explanation">('rural' is the opposite to 'urban')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for rural that I've seen before include "Countrified" , "Rustic" , "Countryfied" , "Bucolic; pastoral" , "Of the country - pastoral" .)
