After midnight, space for curry (5)
I believe the answer is:
groom
'curry' is the definition.
('groom' can be a synonym of 'curry')
'after midnight space' is the wordplay.
'after' says to put letters next to each other.
'midnight' becomes 'g'.
'space' becomes 'room' (room is a kind of space).
'g'+'room' is 'GROOM'.
'for' is the link.
(Other definitions for groom that I've seen before include "man of the match" , "dress?" , "Coach" , "Tidy - stableman" , "Curry - husband-to-be" .)
