I believe the answer is:
lucid
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">easily understandable</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 lucid that I've seen before include "Clear, easily understandable" , "Clear, easily understood" , "Coherent" , "Clear, sane" , "Easy to understand, clearly expressed" .)
