Why do you learn polish?
My father was born in Kolno Poland and taken to a prison camp in 1939 (aged 20). He never saw his family again, and never returned to Poland. I am going to Poland next year and hope to visit his birthplace and also I have found where his parents and brother are buried. I may even have living relatives - I want to know a few sentences at least.
I am currently learning German, and I thought Polish would be a language that would be similar so it would be easier to handle. I was wrong on Polish (it's MUCH harder), but I still like it.
On your question, Poland is a big country, and I don't think many people in Warsaw understand "Ich bin" as much as "Ja jestem"
I try to learn Polish because of I live in a Norway and Polish is the biggest spoken language after Norwegian so it's easy to come in contact with polaks living here and I'm very social. I find them every where I go to. I speak several languages and I find learning Polish as a real challenge because learning f.exp Spanish is not that hard for me but I try to refresh the basic I know from before at the same time.
I try to learn polish because I am married with a half-polish woman. Her mother's family is from Warsaw and some of them don't understand swedish very well. To make it easier to speak with them I thought that it would be useful to know their language. We also want our son to learn both polish and swedish when he grows up, and it makes it much easier if I also know how to speak polish.
I am interested in learning Polish because not only do I enjoy the beauty the language, though my dad and the entire side of the Lázár side of my family were from Hungary or parts of Hungary that are now in Romania and Slovakia, My grandma Lázár's mother my great grandmother Maria, was from Poland, so I have heritage there as well as Hungary, so it's an interesting language to me for heritage reasons but I like learning languages as well.
