Earner Victor on a roll, perhaps? (11)
I believe the answer is:
breadwinner
'earner' is the definition.
(breadwinner is a kind of earner)
'victor on a roll perhaps?' is the wordplay.
'victor' becomes 'winner' ('winner' can be a synonym of 'victor').
'on' is a charade indicator (letters next to each other).
'a roll perhaps?' becomes 'bread' (roll is a kind of bread**).
'winner' put after 'bread' is 'BREADWINNER'.
(Other definitions for breadwinner that I've seen before include "Family's main earner" , "Sole wage earner" , "Family's financial supporter" , "worker" , "Main wage earner" .)
