Finished with a girl 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 a girl' is the wordplay.
'finished' becomes 'done' (similar in meaning).
'with' means one lot of letters go next to another.
'a girl' becomes 'gal' (synonyms).
'done'+'gal'='DONEGAL'
'in' is the link.
Can you help me to learn more?
(Other definitions for donegal that I've seen before include "County of NW Ireland" , "Northernmost Irish county" , "Lean dog (anag) - Irish county" , "Ireland's northmost county" , "town and county" .)
