omit
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">don't include</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for omit that I've seen before include "by-pass" , "Leave something out" , "Leave out or overlook" , "Drop" , "Leave out, perhaps in error" .)
