Containing enthusiasm, almost catch dawn breaking in country (3,7)
I believe the answer is:
new zealand
'country' is the definition.
(New Zealand is an example)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for new zealand that I've seen before include "Antipodean country" , "Land of the kiwi" , "Commonwealth country" , "[TEST TEAM]" , "Zelanian things originate here" .)
