Poems in fact are passed on back to her (4)
I believe the answer is:
odes
'poems' is the definition.
(ode is a kind of poem)
'fact are passed on back to her' is the wordplay.
I cannot really understand how this works, but
'her' could be 'de' and 'de' is found within the answer.
The remaining letters 'os' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for odes that I've seen before include "verse" , "Lyric poems" , "Poems in praise" , "Keats was fond of them" , "Verses" .)
