Finishing with dual nationality? (6,6)
I believe the answer is:
french polish
'finishing' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I don't see?
'dual nationality?' is the wordplay.
I cannot really understand how this works, but
'nationality?' could be 'french' (French is an example) and 'french' is found within the answer.
The remaining letters 'polish' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for french polish that I've seen before include "Shellac dissolved in alcohol, used on furniture" , "bilingually" , "Varnish for furniture" , "Marie Curie was" , "Shiner" .)
