A drink in the shade (6)
I believe the answer is:
spirit
This clue is a double definition.
'a drink' is the first definition.
(I've seen this in other clues)
'the shade' is the second definition.
(I have seen 'A shade' mean 'spirit' so perhaps 'shade' could also mean 'spirit')
'in' acts as a link.
(Other definitions for spirit that I've seen before include "Ghost or animation" , "Liquor or spectre" , "Short" , "enthusiasm" , "Courage; ghost" .)
