Back in profit, I repaired to get drink (8)
I believe the answer is:
aperitif
'drink' is the definition.
(aperitif is a kind of drink)
'back in profit i repaired to' is the wordplay.
'back' says the letters should be written in reverse.
'in' indicates a hidden word.
'fitirepa' is hidden within 'profit i repaired to'.
'fitirepa' backwards is 'APERITIF'.
'get' is the link.
(Other definitions for aperitif that I've seen before include "Appetising drink" , "Preliminary drink" , "Stimulant taken before meal" , "Alcoholic drink to whet the appetite" , "Pre-meal appetiser" .)
