<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">chop off</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for lop that I've seen before include "Remove branches from a tree" , "Cut (e.g. branch off)" , "Hack" , "Cut off, tree branches say" , "Prune, cut the top off" .)
