Feature of general society, too (4)
I believe the answer is:
also
'too' is the definition.
(synonyms)
'feature of general society' is the wordplay.
'feature of' says the answer is hidden in the clue.
'ALSO' is hidden within 'general society'.
(Other definitions for also that I've seen before include "Item" , "'Besides, moreover (4)'" , "into the bargain" , "revolutionary a part for Yugoslavia" , "on top" .)
