If you are a native speaker of English who is just starting to learn Russian, you may not know how to roll your Rs. Russian has two different rolled-R sounds. One is a trilled rolled R, but the more common rolled-R sound is a lightly rolled R that you might use in the Russian word “ruble.”

If you are having a hard time with this sound, start by saying the phrase “Prince of Prussia.”

Then change the phrase to put a lettter D in between the P and the R, and say it again like this: “Pdrince of Pdrussia.”

Say this over and over again, trying to say it faster every time. Keep your jaw closed to the point where you can only fit a fingernail between your back teeth while you do this.

This excercise should help you learn to roll your Rs.
