Drink from the basin (8)
I believe the answer is:
absinthe
'drink' is the definition.
(absinthe is a kind of drink)
'from the basin' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'the'+'basin'='thebasin'
'thebasin' with letters rearranged gives 'ABSINTHE'.
(Other definitions for absinthe that I've seen before include "Bitter liqueur" , "Strong green alcoholic drink" , "Green wormwood drink" , "Green aniseed liqueur" , "Potent aniseed-flavoured drink" .)
