The sound of the Polish 'R'

Learning, what's your native language? (If English, than which dialect).

Most foreigners think that Polish r is a trill, just like the Scottish one, but in fact it's a tap. I mean, you can say it like a Scottish 'r' but it would sound strangely emphasized.

It is just identical with the 't' in 'getting' with standard American pronunciation.

Have you ever heard a polish person say Kurwa?

Once again, there are lots of videos on Youtube that teach you how to roll the 'r'.
