Generalise without real viewing (6)
I believe the answer is:
seeing
'viewing' is the definition.
('see' can be a synonym of 'view')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for seeing that I've seen before include "Noticing" , ". . . . . . is believing, they say" , "Watching" , "Viewing" , "Meeting" .)
