I'm bringing this back up because of a fascinating link on Uncle jazzbeau's page - http://www.dialettando.com/dizionario - a dictionary of Italian dialects. Perusing the word list for the dialect of Emilia Romagna, the region of Italy surroudning San Marino, I found many more examples of this French influence, some that were strikingly obvious, such as "pomm-da-téra" for "patata". Below are are a few more Romagnola words that caught my eye for their similarities to various languages, including, in the case of the first two, English.

bütér : burro
dé : giorno
muiér : moglie
narans: arancia
