<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">prayer ending</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 amen that I've seen before include "Extremist" , "as agreed!" , "So let it be" , "Religiously 11 [THE LASTWORD]" , "Prayer ending" .)
