Change design reportedly for entrance to football stadium? (9)
I believe the answer is:
turnstile
'entrance to football stadium?' is the definition.
(football stadiums usually have turnstiles)
'change design reportedly' is the wordplay.
'change' becomes 'turn' (turn is a kind of change).
'design' becomes 'style' (styling is a kind of designing).
'reportedly' shows a homophone (sound like).
'style' is a homophone of 'stile'.
'turn'+'stile'='TURNSTILE'
'for' acts as a link.
(Other definitions for turnstile that I've seen before include "Admission gate" , "Crowd-controlling gate, at entrance to sports-ground say" , "Means of regulating passage" , "Pivoting gate, to football grounds say" , "Gate admitting one at a time" .)
