Dermot O'Reilly's car? (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
motor
'car?' is the definition.
(motor can informally mean a car)
'dermot o'reilly's' is the wordplay.
'MOTOR' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for motor that I've seen before include "(Transport using) engine" , "Travel by car, engine" , "Engine of vehicle" , "Drive" , "Car (informal)" .)
