Recuperative drink? (3)
I believe the answer is:
cup
'recuperative drink?' is the definition.
'cup' can be an answer for 'drink?' (a cup of drink). I'm not sure about the 'recuperative' bit.
'recuperative drink?' is the wordplay.
'drink?' indicates the answer is hidden within the clue (I've seen 'drinks' mean this (words in the clue have absorbed the answer)).
'CUP' can be found hidden inside 'recuperative'.
Can you help me to learn more?
(Other definitions for cup that I've seen before include "Chalice; trophy" , "Trophy; drinking vessel" , "Container to drink from - prize" , "Prize; vessel" , "Beaker" .)
