Steps over a wall (5)
I believe the answer is:
stile
'steps over a wall' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stile that I've seen before include "Fence crossing" , "Fence-crossing steps" , "Set of steps in a fence or wall" , "Shiny plated metal" , "Steps between fields" .)
