Reza: What I am saying is that in America, if you wanted to say that you are a teacher from Italy, you would never say "I am an Italian teacher". We would not have to worry about putting the accent on one word or another to change the meaning of what we are saying. We would simply state it differently.... "I am an Italian teacher" always means that you teach the Italian language, never that you are a teacher from Italy. If you wanted to say you are a teacher from Italy, you would say it different than "I am an Italian teacher".
