Hi Giovanni!
Over here in THE UNITED STATES of AMERICA, there is an evolutionary process that's ongoing as far as the language we speak... Sort of like a work in progress. Contrary to what the rest of the world may think, we DO NOT speak the same type of english that the english do. In fact, I believe we speak an AMERICAN form of english with a variety of dialects much like the english themselves only alot different and with alot more variety... There are many reasons for the differences as I'm sure you're aware of so, I wo'nt go into them...
I must say to you that it sure is enlightening and refreshing to hear from someone that lives outside of this country regarding the use of "slang" in the way we americans communicate with each other...
I hope that we are'nt unique in that aspect because if that were the case, the rest of the world would be too predictable and we would'nt have a problem communicating with each other or worse, not having to disseminate the slang used in a variety of languages would probably discourage more people in their desire to learn more about the different cultures that exist in countries that are known to use similar languages.
(approaching CRUSH DEPTH!!!) I'll stop here before I get too confusing!!!
One thing that fascinates me is the fact that when it comes to mathematics, engineering & sciences, we all strive very much to speak the same language. Thank goodness for that!!!
Respectfully,
