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.
(I've seen this before)
'driver' is the second definition.
(thesaurus)
'with his own' acts as a link.
This may not be right. 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" .)
