Entrances to new stage (5)
I believe the answer is:
gates
'entrances' is the definition.
(I've seen this in another clue)
'new stage' is the wordplay.
'new' is an anagram indicator.
'stage' anagrammed gives 'GATES'.
'to' is the link.
(Other definitions for gates that I've seen before include "Confines (student) to college; entrances" , "admission?" , "Billionaire computer entrepreneur" , "Microsoft's Bill?" , "philanthropist" .)
