Usage of "tough" letters: ы, ь, and ъ
I found an incredible YouTube video explaining the difference between the Russian hard and soft signs. I have been studying this language for almost six months, and this is the first thing I've come across that really helped me understand. Here's a link: https://www.youtube.com/watch?v=roevsN1zBl4
And, a while back, I bookmarked this video, which really helped me understand how to properly say "ы" (so I decided to share it here, as well): https://www.youtube.com/watch?v=GgwA8FhutKM
Comment with particularly helpful YouTube (or.. whatever site, I guess) videos that explain how Cyrillic letters that are strange to native English speakers are used/said, if you're feeling up to it. :)
I really like her videos, too. She's got a good sense of humor as well, which always makes learning more fun.
