<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">muslim prayer leader</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 imam that I've seen before include "Muslim community leader" , "Islamic religious leader" , "Maim (anag)" , "Prayer-leader in a mosque" , "Muslim religious leader" .)
