Put stop to drink in Irish city (4)
I believe the answer is:
cork
'irish city' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cork that I've seen before include "It's needed for a bottle of wine" , "Wine stopper" , "Irish county - bottle stopper" , "Stopper - Irish port" , "stop" .)
