Order artist to return scope (7)
I believe the answer is:
arrange
'order' is the definition.
(I know that order is a more specific form of arrange)
'artist to return scope' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'to return' says the letters should be written in reverse.
'scope' becomes 'range' (synonyms).
'ra' written backwards gives 'ar'.
'ar'+'range'='ARRANGE'
(Other definitions for arrange that I've seen before include "Marshal" , "Set in place" , "Settle, work out" , "Plan, organize" , "Bring about or put in order" .)
