Poem from Atwood exceptional (3)
I believe the answer is:
ode
'poem' is the definition.
(ode is a type of poem)
'from atwood exceptional' is the wordplay.
'from' says the answer is hidden in the clue.
'ODE' is hidden in the letters of 'atwood exceptional'.
(Other definitions for ode that I've seen before include "Lines" , "(Railway)system" , "poetry" , "Poetic composition" , "Literary work" .)
