Person responsible for keeping an artist in court, possibly (7)
I believe the answer is:
curator
'person' is the definition.
(curator is a kind of person)
'artist in court possibly' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'in' indicates putting letters inside.
'possibly' indicates anagramming the letters.
'court' is an anagram of 'cutor'.
'ra' inserted within 'cutor' is 'CURATOR'.
'responsible for keeping an' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for curator that I've seen before include "Custodian - caretaker" , "Museum's administrative head" , "Cultural employee" , "Custodian of a collection" , "museum boss" .)
