Where Wolfe famously fought the French about nothing (6)
I believe the answer is:
canada
'where wolfe famously fought the french' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'about nothing' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'nothing' becomes 'nada ' (synonyms).
'ca'+'nada'='CANADA'
Can you help me to learn more?
(Other definitions for canada that I've seen before include "Nation in northern North America" , "Country with six time zones" , "Land of the maple leaf" , "Large country" , "See 6 Down" .)
