Some modest verses (4)
I believe the answer is:
odes
'verses' is the definition.
(I've seen this before)
'some modest' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ODES' can be found hidden inside 'modest'.
(Other definitions for odes that I've seen before include "Lines" , "Works by Pindar" , "Verses" , "poetry" , "To a Skylark, To a Nightingale etc" .)
