Artist's workroom (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
studio
'artist's workroom' is the definition.
(I've seen this before)
This is the entire clue.
(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" .)
