Home for some Irish stopper (4)
I believe the answer is:
cork
'stopper' is the definition.
(I know that stopper can be written as cork)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cork that I've seen before include "Type of bark; seal" , "Float" , "Tree used in bottling" , "Stopper; Irish city" , "Irish port - something in a wine bottle?" .)
