Support for an artist (5)
I believe the answer is:
easel
'support for an artist' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for easel that I've seen before include "art supporter" , "Tripod supporting a canvas" , "The rest of artists" , "A stand for blackboard or artist's canvas" , "Painting support" .)
