<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">see-through</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that see-through can be written as transparent)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for transparent that I've seen before include "Sheer" , "Open" , "Unpolluted" , "Frank" , "Obvious - ingenuous" .)
