In real society as well (4)
I believe the answer is:
also
'as well' is the definition.
(synonyms)
'in real society' is the wordplay.
'in' indicates a hidden word.
'ALSO' can be found hidden inside 'real society'.
(Other definitions for also that I've seen before include "Old" , "'Besides, moreover (4)'" , "item's rarely used now for this" , "on top" , "Furthermore" .)
