Study enduring artist (9)
I believe the answer is:
constable
'artist' is the definition.
(I've seen this before)
'study enduring' is the wordplay.
'study' becomes 'con' (con can informally mean to study).
'enduring' becomes 'stable' (I can't justify this - if you can you should believe this answer much more).
'con'+'stable'='CONSTABLE'
Can you help me to learn more?
(Other definitions for constable that I've seen before include "Copper - artist" , "CARRY ON FILM" , "In England, a great painter or lowly policeman" , "PC" , "British painter and police officer" .)
