Prison officer with his own driver (5)
I believe the answer is:
screw
This clue could be a double definition.
'prison officer' is the first definition.
(slang term)
'driver' is the second definition.
(thesaurus)
'with his own' 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 screw that I've seen before include "Archimedes' invention" , "Wood fastener" , "swerve" , "Fastener, rivet" , "Fixer needing driver" .)
