Television screening goddess in French poem (3,5)
I believe the answer is:
the raven
'poem' is the definition.
(poem by Edgar Allan Poe)
'television screening goddess in french' is the wordplay.
'television' becomes 'tv' (synonyms).
'screening' is an insertion indicator (inserted letters are covered or screened by others).
'goddess' becomes 'hera' (Greek goddess).
'in french' becomes 'en' ('in' in French).
'tv' enclosing 'hera' is 'therav'.
'therav'+'en'='THE RAVEN'
(Other definitions for the raven that I've seen before include "Literary bird" , "Poem" .)
