Every individual taking fruit punch at the opening is wasted (4)
I believe the answer is:
each
'every individual' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for each that I've seen before include "Everyone separately" , "...per head" , "Every one of a number" , "Per person" , "This way for a place" .)
