Hurry back to collect official vehicle (6,3)
I believe the answer is:
estate car
'vehicle' is the definition.
(I know that estate car is a type of motor car)
'hurry back to collect official' is the wordplay.
'hurry' becomes 'race' (synonyms).
'back' says the letters should be written backwards.
'to collect' means one lot of letters goes inside another (inserted letters are collected by others).
'official' becomes 'state' (I am not sure about this - if you are sure you should believe this answer much more).
'race' written backwards gives 'ecar'.
'ecar' enclosing 'state' is 'ESTATE-CAR'.
Can you help me to learn more?
(Other definitions for estate car that I've seen before include "Brake" , "Motor vehicle" , "Vehicle for passengers with goods" , "Spacious vehicle" , "Capacious vehicle" .)
