Diana, one experienced artist, repulsed society (7)
I believe the answer is:
artemis
'diana' is the definition.
(I've seen this before)
'one experienced artist repulsed society' is the wordplay.
'one' becomes 'i' (Roman numeral).
'experienced' becomes 'met' (meeting is a kind of experiencing**).
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'repulsed' shows that the letters should be reversed in order.
'society' becomes 's' (common abbreviation in names of organisations).
'i'+'met'+'ra'='imetra'
'imetra' back-to-front is 'artemi'.
'artemi'+'s'='ARTEMIS'
(Other definitions for artemis that I've seen before include "Apollo's twin sister" , "Olympian goddess of hunting" , "Mythical Greek huntress" , "Cynthia" , "Greek goddess of hunting" .)
