Car space entered by Ford model (after reversing) (5)
I believe the answer is:
motor
'car' is the definition.
(motor can informally mean a car)
'space entered by ford model after reversing' is the wordplay.
'space' becomes 'room' (enough space or room to do something).
'entered by' indicates putting letters inside (I've seen this in other clues).
'ford model' becomes 't' (I can't explain this - if you can you should believe this answer much more).
'after reversing' shows that the letters should be reversed in order.
'room' enclosing 't' is 'rotom'.
'rotom' in reverse letter order is 'MOTOR'.
Can you help me to learn more?
(Other definitions for motor that I've seen before include "Engine - relating to movement" , "Drive" , "Car - car's engine" , "Driver" , "Internal combustion engine" .)
