Stand or move gently left (5)
I believe the answer is:
easel
'stand' is the definition.
(easel is a kind of stand)
'move gently left' is the wordplay.
'move gently' becomes 'ease' (synonyms).
'left' becomes 'l' (common abbreviation).
'ease'+'l'='EASEL'
'or' acts as a link.
(Other definitions for easel that I've seen before include "Artist's support frame" , "stand for creativity" , "Blackboard supporter" , "The rest of artists" , "Painter's support" .)
