Two Gentlemen of Verona? (7)
I believe the answer is:
signori
'two gentlemen of verona?' is the definition.
(more than one signor - Italian for 'mister')
'two gentlemen' is the wordplay.
'two gentlemen' can mean two replacements for 'gentleman'.
'gentleman' becomes 'signor' (I have seen 'Italian gentleman' mean 'signor' so perhaps 'gentleman' could also mean 'signor').
'gentleman' becomes 'i' (I can't explain this - if you can you should give a lot more credence to this answer).
'signor'+'i'='SIGNORI'
Can you help me to learn more?
(Other definitions for signori that I've seen before include "Italian gents" , "Italians" , "Italian men" , "men of Roman stamp?" .)
