Break up without a place to walk (4)
I believe the answer is:
kerb
'walk' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for kerb that I've seen before include "Stone edging to footpath" , "Pavement edging" , "Pavement edge" , "Edge of road" , "Pancakes" .)
