<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">goofed</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 erred that I've seen before include "Committed a sin" , "Made a mistake, was wrong" , "Gone astray!" , "slipped up" , "Sinned" .)
