Relieve learner of artist's frame (5)
I believe the answer is:
easel
'artist's frame' is the definition.
(I've seen this before)
'relieve learner' is the wordplay.
'relieve' becomes 'ease' (easing is a kind of relieving).
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'ease'+'l'='EASEL'
'of' is the link.
(Other definitions for easel that I've seen before include "art supporter" , "dead-headed plant" , "board support" , "Artist's wooden frame" , "Lease (anag)" .)
