<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">frond</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for leaf that I've seen before include "needed for making a longer table" , "Thin sheet of metal" , "Tree part - page" , "Part of tree or book" , "Bit of foliage" .)
