Sidewalk (8)
I believe the answer is:
pavement
'sidewalk' is the definition.
(I know that sidewalk can be written as pavement)
This is all the clue.
(Other definitions for pavement that I've seen before include "Pedestrian walkway" , "Footpath" , "Angel --- (J B Priestley)" , "Pedestrians' path" , "Path at the side of a road" .)
