Poem from Isherwood exemplary (3)
I believe the answer is:
ode
'poem' is the definition.
(I know that ode is a type of lyric)
'from isherwood exemplary' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ODE' can be found hidden inside 'isherwood exemplary'.
(Other definitions for ode that I've seen before include "Sung poem" , "Lines" , "Literary work" , "Lyric poem" , "Poem in praise of doe" .)
