There are a few additional letters in the Polish alphabet. The "L" in Lodz isn't an "L" as it has a line going through it, that's a "W" sound.
And the "Z" is actually a "Z" with a line on top. So 'dz' combined make "j" sound. And the o has a line on top which gives it an "oo" sound.
For tomorrow's Polish lesson we will learn to pronounce Szczecin. :)
I can't wait, how do you pronounce 'trzcina'?
Hmmm, sounds like lots of dots and dashes to me! Seriously, a linguist friend of mine once said that Polish and Chinese are the two most difficult languages to learn.
