Person responsible for an artist being in court, perhaps? (7)
I believe the answer is:
curator
'person' is the definition.
(curator is a kind of person)
'an artist being in court perhaps?' is the wordplay.
'an artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'being in' indicates putting letters inside.
'perhaps?' indicates an anagram (I've seen 'perhaps' mean this).
'court' anagrammed gives 'cutor'.
'ra' placed into 'cutor' is 'CURATOR'.
'responsible for' acts as a link.
(Other definitions for curator that I've seen before include "Museum official" , "Museum's administrative head" , "Keeper of a collection" , "Guardian" , "Museum custodian" .)
