Entrances to different stage (5)
I believe the answer is:
gates
'entrances' is the definition.
(I've seen this before)
'different stage' is the wordplay.
'different' indicates an anagram.
'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" .)
