Vermouth? You can drink it with gin (7)
I believe the answer is:
italian
'vermouth?' is the definition.
(Italian vermouth is an example)
'can drink it with gin' is the wordplay.
I cannot really see how this works, but
'drink' could be 'it' and 'it' is present in the answer.
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 italian that I've seen before include "'From Milan or Venice, say (7)'" , "Eg, Native of Turin" , "European tongue" , "This European is anti Lia, oddly" , "of Verona?" .)
