Where the Italians have no age difference? (5)
I believe the answer is:
genoa
'where the italians' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'no age difference?' is the wordplay.
'difference?' indicates an anagram (I've seen 'difference' mean this).
'no'+'age'='noage'
'noage' is an anagram of 'GENOA'.
'have' is the link.
Can you help me to learn more?
(Other definitions for genoa that I've seen before include "Italian city; sail" , "Seaport in northwestern Italy" , "Cake type; foresail" , "North Italian port" , "City of Italy" .)
