Drink it on bail for a change (8)
I believe the answer is:
libation
'drink' is the definition.
(libation is a kind of drink)
'it on bail for a change' is the wordplay.
'for a change' indicates an anagram.
'it'+'on'+'bail'='itonbail'
'itonbail' with letters rearranged gives 'LIBATION'.
(Other definitions for libation that I've seen before include "Drink-offering" , "A serving of an alcoholic beverage" , "Drink poured out as offering to God" , "Ritual of pouring wine as sacrifice to a god" , "Drink poured as offering to the gods" .)
