<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">stocking run</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 ladder that I've seen before include "Household climbing device or tear in stocking" , "something that can send you in the opposite direction?" , "Unravel (as stocking)" , "A fire-fighter may use one" , "Set of rungs" .)
