Clint Eastwood's drink (3)
I believe the answer is:
tea
'clint eastwood's drink' is the definition.
I can't judge whether this definition defines the answer.
'clint eastwood's drink' is the wordplay.
'drink' says the answer is hidden in the clue (I've seen 'drinks' mean this (words in the clue have absorbed the answer)).
'TEA' can be found hidden inside 'clint eastwoods'.
Can you help me to learn more?
(Other definitions for tea that I've seen before include "Beverage; meal" , "and 18 Across: Utensils for afternoon meal" , "Popular beverage brewed at home" , "Light afternoon repast" , "Beverage from leaves" .)
