<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">existent</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for real that I've seen before include "Madrid FC; genuine" , "Actual, not imaginary" , "Type of ale" , "Genuine, not imitation" , "---- Madrid, Spanish football club" .)
