Frenchman's address confusing us in Rome (8)
I believe the answer is:
monsieur
'frenchman's' is the definition.
(I've seen this before)
'confusing us in rome' is the wordplay.
'confusing' is an anagram indicator.
'us'+'in'+'rome'='usinrome'
'usinrome' with letters rearranged gives 'MONSIEUR'.
'address' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for monsieur that I've seen before include "French man" , "Mr or Sir in French" , "Frenchman" , "Belgian's address" , "Frenchman's title" .)
