I believe the answer is:
ignore
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">discount</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that discount can be written as ignore)</span><br/ ><br/ >'<span class="explanation-format__original">disregard</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that disregard can be written as ignore)</span><br/ ><br/ ></span>
(Other definitions for ignore that I've seen before include "Fail to notice (6)" , "Cut head off" , "Deliberately disregard" , "Fail to consider" , "bypass" .)
