I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">dirty-minded</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for lewd that I've seen before include "Sexually crude" , "Indecent, licentious" , "Crude, offensive" , "Salacious" , "Obscene, indecent" .)
