Transportation for men leaving the opera (3)
I believe the answer is:
car
'opera' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for car that I've seen before include "One for the road?" , "Passenger vehicle" , "Hatchback, say?" , "Vehicle carrying vehicles" , "4-wheeled vehicle" .)
