An insect after metamorphosis, for example (8)
I believe the answer is:
instance
'example' is the definition.
('instance' can be a synonym of 'example')
'an insect after metamorphosis' is the wordplay.
'after' says to put letters next to each other.
'metamorphosis' is an anagram indicator.
'an'+'insect'='aninsect'
'aninsect' anagrammed gives 'INSTANCE'.
'for' acts as a link.
(Other definitions for instance that I've seen before include "Cite as an example" , "A case or example of something" , "Case in point" , "Specimen" , "Case or example from ancients" .)
