Falseness breaks your spirit -- right to be ousted by society (10)

'falseness' is the definition.

'breaks your spirit right to be ousted by society' is the wordplay.
I cannot quite see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
'be' could be 'sit' (sitting is a kind of being) and 'sit' is located in the answer.
'society' could be 's' (common abbreviation in names of organisations) and 's' is found within the answer.
This explanation may well be incorrect...
