Just starting old Danish epic poem (3)
I believe the answer is:
ode
'poem' is the definition.
(ode is a kind of poem)
'just starting old danish epic' is the wordplay.
'just starting' says to take the initial letters.
The first letters of 'old danish epic' is 'ODE'.
(Other definitions for ode that I've seen before include "Poem in praise of doe" , "(Railway)system" , "- - to a 12 Urn" , "poetry" , "Lines" .)
