<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">incalculable</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 untold that I've seen before include "Lots" , "Too many to be counted; not narrated" , "missing relations" , "Not narrated or measured" , "Story yet to be read" .)
