Chauffeur (6)
I believe the answer is:
driver
'chauffeur' is the definition.
(I know that chauffeur can be written as driver)
This is the entire clue.
(Other definitions for driver that I've seen before include "Golf-club for a motorist" , "Member of RAC" , "Type of golf club" , "Operator of a motor vehicle" , "Motorist - golf club" .)
