<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">artist's workroom</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 studio that I've seen before include "Where one might find artists" , "Workshop for 27 dn" , "RA's workroom" , "Workplace for the practice of art" , "Unpleasant vapour" .)
