<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">for the second time</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 again that I've seen before include "Anew" , "On the other hand" , "Here we go ___" , "Not for the first time" , "Furthermore" .)
