Wine forced on some Irishmen (7)
I believe the answer is:
madeira
'wine' is the definition.
(I know this)
'forced on some irishmen' is the wordplay.
'forced' becomes 'made' (I've seen this before).
'on some irishmen' becomes 'ira' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'made'+'ira'='MADEIRA'
Can you help me to learn more?
(Other definitions for madeira that I've seen before include "Cake - wine" , "Island in the Atlantic Ocean" , "Atlantic island, famed for its sweet wine" , "Fortified white wine from island off NW Africa" , "Dessert wine from a Portuguese Atlantic island" .)
