Smell in Rome, locally (5)
I believe the answer is:
aroma
'smell' is the definition.
(aroma is a kind of smell)
'rome locally' is the wordplay.
I cannot quite understand how this works, but
'rome' could be 'roma' (synonyms) and 'roma' is present in the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for aroma that I've seen before include "Perfume" , "Test of knowledge" , "Pervasive quality" , "particular charm" , "Pervasive atmosphere" .)
