Is able to name a country (6)
I believe the answer is:
canada
'country' is the definition.
(I know that Canada is North American country)
'is able to name a' is the wordplay.
'is able to' becomes 'can' (if you can do something you are able to do it).
'name' becomes 'Ad'.
'can'+'ad'+'a'='CANADA'
(Other definitions for canada that I've seen before include "Country of 32 ac" , "Its flag includes the maple leaf" , "North American goose" , "N American country" , "Land of the maple leaf" .)
