Entrances to different stage (5)
I believe the answer is:
gates
'entrances' is the definition.
(I've seen this in another clue)
'different stage' is the wordplay.
'different' indicates an anagram (letters placed in a different order).
'stage' with letters rearranged gives 'GATES'.
'to' is the link.
(Other definitions for gates that I've seen before include "Moveable barriers" , "Openings" , "Hinged barriers serving as entrances" , "Entrances (for Bill?)" , "Rich American" .)
