One's driven, say, to interrupt regressing career (6,3)
I believe the answer is:
estate car
'one's driven' is the definition.
I can't tell whether this defines the answer.
'say to interrupt regressing career' is the wordplay.
'say' becomes 'state' (synonyms).
'to interrupt' indicates putting letters inside.
'regressing' says the letters should be written backwards (to regress is to go backwards).
'career' becomes 'race' (career can mean to race around).
'race' backwards is 'ecar'.
'state' going into 'ecar' is 'ESTATE-CAR'.
Can you help me to learn more?
(Other definitions for estate car that I've seen before include "Vehicle for passengers with goods" , "Capacious vehicle" , "Vehicle with five doors" , "Motor vehicle" , "Brake" .)
