<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">took no notice of</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 ignored that I've seen before include "Failed to notice" , "Turned a blind eye to" , "Left out in the cold" , "Passed over" , "Took no notice of" .)
