Popular viewpoint for example (8)
I believe the answer is:
instance
'example' is the definition.
('instance' can be a synonym of 'example')
'popular viewpoint' is the wordplay.
'popular' becomes 'in'.
'viewpoint' becomes 'stance' (I've seen this before).
'in'+'stance'='INSTANCE'
'for' is the link.
(Other definitions for instance that I've seen before include "Occasion" , "Specimen" , "Case - isn't acne (anag)" , "Particular case; cite" , "Canniest (anag) - occurrence" .)
