The penalties of strife perhaps (8)
I believe the answer is:
forfeits
'the penalties' is the definition.
(forfeit is a kind of penalty)
'of strife perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'of'+'strife'='ofstrife'
'ofstrife' is an anagram of 'FORFEITS'.
(Other definitions for forfeits that I've seen before include "Things paid or given as penalties" , "Gives up, sacrifices" .)
