Example within adopted attitude (8)
I believe the answer is:
instance
'example' is the definition.
(I know that example can be written as instance)
'within adopted attitude' is the wordplay.
'within' becomes 'in'.
'adopted attitude' becomes 'stance' (stance is a kind of attitude. I am not sure about the 'adopted' bit.).
'in'+'stance'='INSTANCE'
Can you help me to learn more?
(Other definitions for instance that I've seen before include "A case or example of something" , "Case in point" , "Exemplify" , "Case or example from ancients" , "Specimen" .)
