If you’ve vision, there’s opportunity (5)
I believe the answer is:
scope
'opportunity' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scope that I've seen before include "Capacity" , "Range of action" , "Extent; viewer (colloq.)" , "Extent; latitude" , "Range, compass" .)
