<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">espy</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that espy can be written as spot)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for spot that I've seen before include "See 5" , "Small mark or stain" , "Difficult situation" , "Discern - mark" , "See - speckle" .)
