Equality accepted and shared (8)
I believe the answer is:
partaken
'shared' is the definition.
(partaking is a kind of sharing)
'equality accepted' is the wordplay.
'equality' becomes 'par' (synonyms).
'accepted' becomes 'taken' ('take' can be a synonym of 'accept').
'par'+'taken'='PARTAKEN'
'and' acts as a link.
(Other definitions for partaken that I've seen before include "Joined" , "Shared" , "Participated" , "Eaten some (of food/drink)" .)
