I wish there was a distinction between "English" and "American". My first language is American, then some Italian, French, German, Flemish, and Kings English in that order.

@ Lord of Dans:

Have you tried your Portuguese in Brazil or oddly enough the Lazio region of Italy?

I was on a project in Aprilla, Latina and some of the start-up staff were pulled from our Sao Paulo division. Although their native tongue was Portuguese, they told me they were better understood and felt more at home on site in that region of Italy then they did when they visited Portugal or other areas of Italy over long week-ends for R & R.
