<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">religious pamphlet</span>' is the definition.<br/ ><span class="explanation-format__explanation">(tract is a type of pamphlet)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for tract that I've seen before include "Extensive area of land" , "Pamphlet; area of land" , "Short treatise; land area" , "Large area; pamphlet" , "religious work, often" .)
