If you want to say it with emotion, then say it in Italian.
There
are no people on earth and no language more beautiful than that of our
Italian friends. When you make an expressive or romantic
statement using the word "beautiful" in Italian, you can be sure that it
will be received as the ultimate adulation or compliment.
When spoken, "beautiful"
in Italian simply sounds beautiful. Bella, "beautiful" in Italian, is
the only Italian word used to describe beautiful. So choose your subjects carefully when lavishing them with your Italian admiration for their beauty.
