<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">failed to hit</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 missed that I've seen before include "Failed to hit target" , "Failed to catch" , "Skipped" , "Omitted" , "failed to see" .)
