He sees you clutch the drink sent out (8)
I believe the answer is:
beholder
'he sees' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'clutch the drink sent out' is the wordplay.
I cannot really understand how this works, but
'clutch' could be 'hold' (synonyms) and 'hold' is found in the answer.
'drink' could be 'beer' (beer is a kind of drink) and 'beer' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'you' is the link.
Can you help me to learn more?
(Other definitions for beholder that I've seen before include "Some looker" , "Beauty is said to be in this eye" , "Witness" , "Observer" , "Onlooker" .)
