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