Has anyone heard the Lakhota language spoken? I can't say that I've heard a lot of other (non-English) languages spoken, but of all the languages that I've heard, Lakhota sounds the most beautiful. I tried studying it when I was younger and would love to be able to speak it fluently, it truly is a beautiful sounding language.
I took 4 years of Latin in high school, and all I have to show for it is "Duo Romani puellae, nomine Aurelia et Flavia, sedent sub arbore et cantant."

Actually, by taking Lating I leared a lot about English, not just interesting derivitives, but the structure of the English language and how it differs from other languages (such as Latin).
In the past I've dabbled in Greek, Russian, and Italian; and I think Middle Eastern languages would be interesting to learn.
I would
really (!) like to learn Czech since a big branch of my family tree originates from Prague.
