Rap vile sort of win (7)
I believe the answer is:
prevail
'win' is the definition.
(I know this)
'rap vile sort' is the wordplay.
'sort' indicates anagramming the letters.
'rap'+'vile'='rapvile'
'rapvile' is an anagram of 'PREVAIL'.
'of' is the link.
(Other definitions for prevail that I've seen before include "Triumph, overcome" , "Successfully persuade" , "Be widespread; prove superior" , "Prove more powerful" , "Be victorious" .)
