Example item Poe adapted (7)
I believe the answer is:
epitome
'example' is the definition.
(epitome is a kind of example)
'item poe adapted' is the wordplay.
'adapted' indicates an anagram.
'item'+'poe'='itempoe'
'itempoe' anagrammed gives 'EPITOME'.
(Other definitions for epitome that I've seen before include "classic example" , "Model" , "Archetype, typical example" , "Digest" , "Summary; embodiment" .)
