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 quite see how this works, but
'month' could be 'mar' (short for March) and 'mar' is found in the answer.
'can' could be 'tin' (both are metal containers) and 'tin' is located in the answer.
'i' is present in the answer.
No letters remain.
This explanation may well be incorrect...
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" .)
