The worse for wear, having only gin to drink? (3,2,2)
I believe the answer is:
out of it
'the worse for wear' is the definition.
(both can mean drunk)
'only gin to drink?' is the wordplay.
I cannot quite understand how this works, but
'to' is within the answer.
'drink?' could be 'it' and 'it' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'having' acts as a link.
Can you help me to learn more?
(Other definitions for out of it that I've seen before include "Excluded from participation" , "is not included" , "unaware of what's going on" , "Eliminated" , "Drunk < , unaware what is happening" .)
