In the morning I race around a continent (7)
I believe the answer is:
america
'a continent' is the definition.
(the Americas can be considered as one continent)
'in the morning i race around' is the wordplay.
'in the morning' becomes 'am' (AM on a clock).
'around' is an anagram indicator.
'i'+'race'='irace'
'irace' is an anagram of 'erica'.
'am'+'erica'='AMERICA'
(Other definitions for america that I've seen before include "Camera I turn on the continent" , "huge landmass" , "Land of the free and home of the brave?" , "The US" , "World power" .)
