Country with actual borders in another country (9)
I believe the answer is:
australia
'country' is the definition.
(I know that Australia is a country)
'actual borders in another country' is the wordplay.
'borders' says to hollow out the word (remove centre letters) (only the edge or border letters remain).
'in' indicates putting letters inside.
'another country' becomes 'austria' (Austria is an example. I am not sure about the 'another' bit.).
'actual' with its centre removed is 'al'.
'al' put within 'austria' is 'AUSTRALIA'.
'with' is the link.
Can you help me to learn more?
(Other definitions for australia that I've seen before include "USA lariat found down under" , "Norfolk and Christmas Islands belong to it" , "Barry Humphries' birthplace" , "Antipodean continent" , "Commonwealth member" .)
