<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">in a good way</span>' is the definition.<br/ ><span class="explanation-format__explanation">(to do something well is to do it in a good way)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for well that I've seen before include "Very much; healthy" , "four-letter word repeated in Shakespeare comedy" , "Waterhole; healthy" , "run" , "Sound" .)
