<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">polytheist</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for pagan that I've seen before include "Unbeliever" , "Heathen; non-believer" , "Polytheist" , "One who follows a polytheistic or pre-Christian religion, but not a Jew" , "Not conventionally religious" .)
