I find languages and linguistics fascinating. I love English so much, but have an affection for so many other languages as well (Spanish, German, French, Arabic, Modern Greek and Italian, as well as the
schtickle of Yiddish I have learned over the years.).
I just read a very interesting article on the Italian language the other day, and how it has changed in use in America with the long presence of Italian -Americans, over time (particularly its usage in New Jersey.). Very interesting!
Many Educational psychologists do feel that continually refreshing our language skills or even learning a new language helps keep the brain sharp.
Thanks for the recommendation, Lokebee.
