Heard to wander in Italy
I believe the answer is:
rome
'in italy' is the definition.
('Rome' is part of 'italy')
'heard to wander' is the wordplay.
'heard' shows a homophone (sound like).
'to wander' becomes 'roam' (synonyms).
'roam' is a homophone of 'ROME'.
(Other definitions for rome that I've seen before include "Capital city" , "Where to emulate the locals" , "Spanish Steps city" , "European capital" , "When there, do as the native do" .)
