A drink with no body to it (6)
I believe the answer is:
spirit
'a drink' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for spirit that I've seen before include "bottle?" , "Phantom, ghost" , "Ghost or strong drink" , "eg Whisky or gin" , "Ghost or soul" .)
