Is able to name a distant land (6)
I believe the answer is:
canada
'distant land' is the definition.
'Canada' can be an answer for 'land' (Canada is an example). I am unsure of the 'distant' bit.
'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'
Can you help me to learn more?
(Other definitions for canada that I've seen before include "Country to north of USA" , "See 6 Down" , "North American goose" , "North American country" , "Land of the Great Lakes" .)
