A stand for art (5)
I believe the answer is:
easel
'a stand' is the definition.
(easel is a kind of stand)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for easel that I've seen before include "Artist's prop" , "dead-headed plant" , "Constable's stand?" , "the rest of the paintwork" , "Board stanchion" .)
