Villains have run over visitor, severing foot (6)
I believe the answer is:
rogues
'villains' is the definition.
(rogue is a kind of villain)
'run over visitor severing foot' is the wordplay.
I cannot really see how this works, but
'run' could be 'r' (cricket abbreviation) and 'r' is located in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is located in the answer.
The remaining letters 'gues' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'have' is the link.
Can you help me to learn more?
(Other definitions for rogues that I've seen before include "'Dishonest, unscrupulous persons (6)'" , "Rascals" , "Scoundrels, miscreants" , "'Scoundrels, charlatans (6)'" , "Wild animals driven away from the herd" .)
