Continent I discovered in camera snap (7)
I believe the answer is:
america
'continent' is the definition.
(the Americas can be considered as one continent)
'i discovered in camera snap' is the wordplay.
'discovered in' is an insertion indicator.
'snap' indicates anagramming the letters (letters snap or break).
'camera' is an anagram of 'amerca'.
'i' going within 'amerca' is 'AMERICA'.
(Other definitions for america that I've seen before include "Ira came from the continent" , "Camera I turn on the continent" , "Camera I take to the continent, oddly" , "Take care and aim for the continent" , "Camera I used in New World" .)
