The current drink (7)
I believe the answer is:
draught
I believe this is a double definition.
'the current' is the first definition.
(thesaurus)
'drink' is the second definition.
(I've seen this before)
(Other definitions for draught that I've seen before include "Indoor breeze" , "Slug" , "intake" , "wind" , "Current - drink - drawing - checker" .)
