After short month, can I drink? (7)
I believe the answer is:
martini
'drink?' is the definition.
(martini is a kind of drink)
'after short month can i' is the wordplay.
I cannot really understand how this works, but
'month' could be 'mar' (short for March) and 'mar' is found within the answer.
'can' could be 'tin' (both are metal containers) and 'tin' is found in the answer.
'i' is 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 martini that I've seen before include "Alternative name for Simone Memmi, pre-Renaissance Italian painter" , "Type of Italian vermouth" , "In glass, one's dry" , "James Bond's drink of choice" , "rifle" .)
