Hi RocĂo,
If I write the pronunciation of your name in English, it would be Roe-SEE-oh.
And it means "dew" if I'm not mistaken.
Another interesting name I've heard on my Spanish journey would be a place name: Roncesvalles. It's interesting because in my city, Toronto, there's a long street with that name, and of course the people here pronounce it nothing like they would in Spanish-speaking countries. Many years ago, I bicycled around Spain and by chance I passed through the place called Roncesvalles there. So that experience will be forever memorable.
Also, I just have to tell you that I looked at your introduction video on this site and, de vĂŠras, you probably have the best introduction video on italki. So clear, so friendly, and so much enthusiasm!
Hey, everybody: Make your videos more like RocĂo's!
