Doorman for very lively ball (7)
I believe the answer is:
bouncer
This clue could be a double definition.
'doorman' is the first definition.
(security guard stationed at a door)
'lively ball' is the second definition.
(I've seen this before)
'for very' acts as a link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for bouncer that I've seen before include "Chucker-out for nightclub" , "Bumper" , "Lively ball" , "Cricket delivery - employee ejecting troublemakers" , "cheque that's worthless?" .)
