A vice’s all right (6)
I believe the answer is:
agreed
'all right' is the definition.
(thesaurus)
'a vice's' is the wordplay.
'vice' becomes 'greed' (I've seen this before).
'a'+'greed'='AGREED'
(Other definitions for agreed that I've seen before include "Geared (anag.)" , "That's right" , "Mutually settled" , "came to the same conclusion" , "I'll go along with that" .)
