Finished with lass in Ireland (7)
I believe the answer is:
donegal
'ireland' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'finished with lass' is the wordplay.
'finished' becomes 'done' (both can mean completed).
'with' is a charade indicator (letters next to each other).
'lass' becomes 'gal' (both can mean a girl).
'done'+'gal'='DONEGAL'
'in' is the link.
Can you help me to learn more?
(Other definitions for donegal that I've seen before include "part of Ireland" , "Irish town" , "Lean dog (anag) - Irish county" , "Ireland's northmost county" , "Northernmost Irish county" .)
