Model's poem (3)
I believe the answer is:
ode
'poem' is the definition.
(ode is a type of poem)
'model's' is the wordplay.
'ODE' is hidden within the letters.
But, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for ode that I've seen before include "A poem celebrating person or event" , "(Railway)system" , "poetry" , "- - to a 12 Urn" , "Poem expressing noble feelings" .)
