End of a prayer (4)
I believe the answer is:
amen
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">end of a prayer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for amen that I've seen before include "statement of affirmation" , "prayer's ending" , "Extremist" , "Prayerful last word" , "Name for prayer's end" .)
