Writer married to Italian poet and philosopher endlessly producing a hanging ornament (7)
I believe the answer is:
pendant
'a hanging ornament' is the definition.
(I've seen this in another clue)
'writer married to italian poet and philosopher endlessly' is the wordplay.
I cannot quite understand how this works, but
'writer' could be 'pen' (something which writes) and 'pen' is located in the answer.
an anagram of 'and' is 'dan' which is located in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'producing' is the link.
Can you help me to learn more?
(Other definitions for pendant that I've seen before include "Ornament hanging from a piece of jewellery" , "Panted after learned one" , "earring, say" , "Hanging light" , "One hung by the neck" .)
