<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">campus area</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 quad that I've seen before include "Court" , "college square?" , "space found in building" , "Square amid buildings" , "Rectangular area with buildings on all sides" .)
