As well as members of real society (4)
I believe the answer is:
also
'as well as' is the definition.
(I've seen this in another clue)
'members of real society' is the wordplay.
'members of' says the answer is hidden in the clue (the letters are 'members' of the clue).
'ALSO' is hidden in the letters of 'real society'.
(Other definitions for also that I've seen before include "admitted to Royal Society > too" , "Furthermore" , "What's more" , "in accompaniment" , "'Besides, moreover (4)'" .)
