A superintendent too poetic about poetry (8)
I believe the answer is:
overseer
'a superintendent' is the definition.
(I know that superintendent can be written as overseer)
'too poetic about poetry' is the wordplay.
'too poetic' becomes 'oer' (I can't justify this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'poetry' becomes 'verse' (synonyms).
'oer' enclosing 'verse' is 'OVERSEER'.
Can you help me to learn more?
(Other definitions for overseer that I've seen before include "who is put in charge" , "gaffer" , "monitor" , "Person supervising" , "One manages" .)
