Country where one caught antelope (7)
'country' is the definition.
(Iceland is an example)
'one caught antelope' is the wordplay.
'one' becomes 'I' (roman numeral).
'caught' becomes 'c' (cricket abbreviation).
'antelope' becomes 'eland' (eland is a kind of antelope).
'where' acts as a link.
(Other definitions for iceland that I've seen before include "Its capital is Reykavik", "Home to the volcano Eyjafjallajokull", "North Atlantic island republic", "Land of geysers and Norse sagas", "Nice lad (anag)".)
