Lofty accommodation of some shifty retailers (7)
I believe the answer is:
atelier
This could be a double definition.
'lofty accommodation' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'of some shifty retailers' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for atelier that I've seen before include "Artist's workroom" , "I relate to workshop used by artist" , "Designer's workshop" , "Artist's workshop, studio" , "Tie earl up in the artist's place" .)
