A student leaves one country for another (7)
I believe the answer is:
austria
'a student' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'one country for another' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'country' could be 'us' (US is an example) and 'us' is located in the answer.
'another' could be 'r' (I've seen this in other clues) and 'r' is found within the answer.
This explanation may well be incorrect...
'leaves' is the link.
Can you help me to learn more?
(Other definitions for austria that I've seen before include "Landlocked European country" , "German-speaking republic" , "EU member" , "part of Europe" , "land in Europe" .)
