New map covering a North American country (6)
I believe the answer is:
panama
'country' is the definition.
(Panama is an example)
'new map covering a north american' is the wordplay.
'new' indicates anagramming the letters.
'covering' indicates putting letters inside.
'north american' becomes 'na'.
'map' with letters rearranged gives 'pma'.
'a'+'na'='ana'
'pma' going around 'ana' is 'PANAMA'.
(Other definitions for panama that I've seen before include "Style of hat" , "Hat made of plaited palm leaves" , "Country and straw hat" , "Hat woven from jipijapa leaves" , "A great canal or a straw hat" .)
