Liqueur akin to sambuca (8)
I believe the answer is:
anisette
'liqueur akin to sambuca' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anisette that I've seen before include "Type of highly-flavoured liqueur" , "[APERITIF]" , "Liquorice flavoured liqueur" , "Aromatic cordial drink" , "Strong-flavoured liqueur" .)
