<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">lacking originality</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 banal that I've seen before include "lacking interest?" , "Tediously unoriginal" , "Ordinary and uninteresting" , "Tediously commonplace" , "flat" .)
