Reception area for you to enter? (5)
I believe the answer is:
foyer
'reception area' is the definition.
(I've seen this before)
'for you to enter?' is the wordplay.
'you' becomes 'ye' (historical version of 'you').
'to enter?' indicates putting letters inside.
'for' enclosing 'ye' is 'FOYER'.
(Other definitions for foyer that I've seen before include "Large entrance area" , "Reception room or waiting area" , "Theatrical" , "Anteroom" , "Theatre entrance hall" .)
