Bail into complex for a drink (8)
I believe the answer is:
libation
'for a drink' is the definition.
(libation is a kind of drink)
'bail into complex' is the wordplay.
'complex' is an anagram indicator.
'bail'+'into'='bailinto'
'bailinto' with letters rearranged gives 'LIBATION'.
(Other definitions for libation that I've seen before include "Drink poured as offering to the gods" , "Ritual of pouring wine as sacrifice to a god" , "Alcoholic drink" , "Liquid offering" , "A serving of an alcoholic beverage" .)
