Where, in Italy, poetry heartens the new man (6)
I believe the answer is:
modena
'where in italy' is the definition.
The definition suggests a singular noun which matches the answer.
'poetry heartens the new man' is the wordplay.
I cannot quite understand how this works, but
'poetry' could be 'ode' (I've seen this before) and 'ode' is located in the answer.
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is located in the answer.
'man' could be 'm' and 'm' is located in the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for modena that I've seen before include "City of northern Italy" , "Domestic fancy pigeon" , "Crimson" .)
