Contemplate large drink or experience its effect? (3,6)
I believe the answer is:
see double
'contemplate large' is the definition.
I can't tell whether this defines the answer.
'drink or experience its effect?' is the wordplay.
I cannot quite understand how this works, but
'drink' could be 'double' (double shot of alcohol) and 'double' is located in the answer.
'experience' could be 'see' (seeing is a kind of experiencing) and 'see' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for see double that I've seen before include "experience an illusion" , "Drunks might well" , "Observe two of everything" .)
