Does one put brakes on Rover? (5)
I believe the answer is:
leash
This clue could be a double definition.
'does one' is the first definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'brakes on rover?' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'put' is the link.
Can you help me to learn more?
(Other definitions for leash that I've seen before include "Restraint for a dog" , "Bind" , "Rope used to restrain an animal" , "Dog lead" , "Line for holding dog" .)
