Model reveals some poetry (3)
I believe the answer is:
ode
'poetry' is the definition.
(ode is a type of poem)
'model reveals some' is the wordplay.
'some' says the answer is hidden in the clue.
'ODE' is hidden within 'model reveals'.
(Other definitions for ode that I've seen before include "Poem expressing noble feelings" , "A poem celebrating person or event" , "- - to a 12 Urn" , "Poem in praise of doe" , "Verse form" .)
