Artist who might be going round the bend? (6)
I believe the answer is:
turner
'artist who might be going' is the definition.
'turner' can be an answer for 'artist' (painter JMW Turner). I'm not sure about the remainder of the definition.
'round the bend?' is the wordplay.
'round' becomes 'turn' (synonyms).
'the bend?' becomes 'er' (I am not sure about this - if you are sure you should believe this answer much more).
'turn'+'er'='TURNER'
Can you help me to learn more?
(Other definitions for turner that I've seen before include "JMW ------, English artist renowned for his land- and sea-scapes" , "potter" , "Skilled tradesman or great English painter." , "one engaged in revolutionary movement" , "revolutionary type?" .)
